I’m building a fully-fledged decentralized application and I’m looking for an experienced blockchain developer to bring it to life from concept to main-net launch. The exact chain is still open, so your insight on whether Ethereum, Binance Smart Chain, Polygon, or another EVM-compatible network best serves the project will be invaluable. Here’s what I need from you: • Architect and code the smart contracts that power the core logic of the dApp, following current security best practices and making sure the code is upgrade-friendly. • Set up the back-end infrastructure (nodes, indexers, or hosted solutions such as Infura/Alchemy/Moralis) and connect it cleanly to the front end. • Build or integrate the web/mobile front end so users can interact with t...
I run a café and I’m ready to replace printed menus with a QR-based, modern-looking digital menu that lets guests order straight from their phones. When a customer scans the code, they should land on a clean, sleek interface that presents all our food and beverage options, organised in an intuitive way and easy to update later on my side. The flow I need is simple: guest scans → browses menu → taps to place items in a cart → hits “Send order” → a formatted message (item names, quantities, table number or pickup note, total) is pushed directly to my WhatsApp number. From there my staff can reply to confirm or ask a question, so no extra dashboards are required. Core deliverables • Customised QR code that points to the live menu • Re...

I’m ready to turn an idea into a working Chrome extension that makes it easier to land roles listed on Amazon Jobs. At this stage I know the core requirement: the add-on must run smoothly in Google Chrome and integrate directly with the Amazon Jobs site. Beyond that, I’m open to building in whichever features will give candidates the biggest advantage—whether that ends up being live job alerts, streamlined application auto-fill, advanced filtering or a thoughtful mix of all three. Here’s what I’m looking for you to do: • Help define the exact feature set and workflow after a quick discovery chat. • Design a clean, intuitive UI that feels native inside Chrome. • Build the extension with best-practice front-end tooling (Manifest V3, JavaScript/T...

I already own the WordPress theme and hosting; what I now need is a specialist who can turn that blank install into a finished, customer-ready website that cleanly showcases our services and products. Scope of work • Replicate the theme’s demo layout page-for-page, keeping its full-width sections, spacing and interactions. • Apply a modern, minimalist colour palette and typography that complements the template. • Build out all navigation: main menu, any dropdowns, sticky header behaviour and a clear footer with key links. • Style every button, form and call-to-action so they feel native to the theme. • Position placeholder text blocks and image areas so I can simply drop our final copy and photos in later. • Optimise every element for seamle...
My current site needs a thorough refresh that touches content, design, and a few functional areas. Content first: I will supply revised copy and new imagery, and I need you to replace existing text, swap in the fresh images, and create several brand-new pages so the navigation feels seamless. On the design side, the whole layout needs re-thinking for better flow and modern aesthetics. I’m open to your creative direction on grids, spacing, and component hierarchy, but the final result must stay on brand. While the colour palette will remain, please refine typography—font pairings, sizes, and line-height—to boost readability across desktop and mobile. Functionality improvements are lighter but important: tidy up any broken links, optimise load speed, and ensure new p...

My WordPress site runs an old, non-updatable version of Elementor and both embedded contact forms throw a specific error as soon as the Send button is pressed. Pages load perfectly; the problem appears only on submission. I don’t need a rebuild or a plugin overhaul—just get at least one of these existing Elementor forms to submit successfully and deliver the messages to my mailbox. Rolling back or upgrading the entire site isn’t an option right now, so the fix must work with the present Elementor version and the active theme. Deliverable: • A working contact form on the live site, tested end-to-end with a confirmation message and email delivery. Once I click Send and receive the test email without that error, the job is done.
I’m building an internal control panel that streamlines our customer-support workflow. The stack is Python with Streamlit for the UI, Redis for fast in-memory state and queueing, and Postgres as the source of truth for historical data. Core workflow The panel’s single purpose is to let our support team handle live customer interactions from one place. Agents must be able to launch or join an active chat, see who is waiting, review basic customer context pulled from Postgres, and hand the conversation off or close it. All updates to chat status should push instantly to every connected agent, so WebSocket or Streamlit’s native realtime features will be necessary. Key feature set • Live chat integration that plugs into our existing WebSocket gateway (or a lightwei...
I want a clean, responsive informational blog built from the ground up (or on a well-supported CMS such as WordPress or a lightweight static-site generator—whichever suits the project best). The aim is to publish articles regularly, so readability, fast load times, and an intuitive back-end for posting are essential. Two functional pieces must be in place from day one: • A REGULAR emailing section beneath each post that is easy to moderate and deters spam • A FULLY PAID subscription form that captures visitors’ FINANCIAL VIA STRIPE & emails and funnels them to a list I can manage in Mailchimp or a comparable service THIS IS VERY IMPORTANT. Beyond those, I expect modern SEO fundamentals, cross-browser compatibility, and mobile-first responsiveness. I w...
I’m ready to give my existing site a fresh, modern look and feel. The priority is a complete upgrade of the visual design and overall user interface so visitors immediately sense a polished, contemporary brand the moment they land on any page. The style should feel modern and sleek—think generous whitespace, smooth micro-interactions, crisp icons, and a cohesive colour palette that aligns with our current logo. Responsive behaviour on desktop, tablet, and mobile is essential, and I’m keen to see subtle motion (CSS transitions or lightweight animations) where it enhances the user journey without slowing things down. Deliverables I’d like from you: • High-fidelity mock-ups or Figma/Adobe XD files for each page listed above. • Final front-end assets (HTML...
My WordPress store, , is due for a visual upgrade. I want the front-end modernized into a clean, corporate-professional look while every category, tag, permalink, and indexed page structure stays exactly where it is so my current Google rankings remain intact. Core goals are simple: a design refresh that feels trustworthy and premium, navigation that lets customers reach any product in two taps or clicks, seamless mobile responsiveness, lightning-fast load times, and on-page AI optimisation (schema, meta prompts, content placement ready for future AI-driven features). Conversions should rise naturally from the clearer user journey and faster pages, but I don’t want any risky SEO experiments—no URLs, slugs, or taxonomies may change. Deliverables • New WordPress theme or...
My Shopify store, , is up and running with every product already loaded; what it lacks is the fresh, bold energy I have in mind. I want the entire storefront—layout, color palette, typography, imagery, and graphic accents—to feel vibrant and modern without touching the underlying product data or rebuilding the theme from scratch. Here’s what I need: a designer‐developer who can jump into the Shopify Theme Editor (or work directly in Liquid, CSS, and a bit of JavaScript) and re-style the existing theme. Think striking colors, confident type choices, and a layout that guides customers intuitively from homepage to checkout while showcasing the toughness of our tarp products. Key deliverables • Updated layout structure across all core templates (home, collection, produ...
Project Description: I am looking for an experienced full-stack developer (preferably with blockchain/DeFi knowledge) to create a high-quality, modern cryptocurrency price oracle scanner and monitoring platform, closely inspired by — specifically the "BTC Oracle Scanner" tool. This site is not a full publishing oracle like Chainlink or Pyth (i.e., it does not need to push data on-chain initially), but rather a powerful real-time monitoring, deviation detection, latency tracking, and anomaly alerting dashboard that compares BTC/USD (and potentially other assets) prices across multiple sources: CEXs, oracles, DEXs, and wrapped/bridge tokens. Core Goal & Inspiration Replicate and improve upon the functionality of : Real-time BTC/USD price pulling and comparison every few...

My React 18 + Vite project has grown quickly and now feels sluggish and hard to navigate. I need an experienced full-stack engineer to step in, audit the codebase, and leave it faster, cleaner, and bug-free. Here’s where the pain shows up: performance drops on first paint, confusing file structure, and a handful of stubborn functionality bugs. The most obvious trouble spots are the navigation bar, several form flows, and scattered UI elements. I already maintain an internal style guide covering naming, folder hierarchy, linting rules, and testing conventions, so every change must line up with those guidelines. You’ll profile the bundle, refactor any tangled components, trim redundant state, fix the visible glitches, and push everything through Vite’s dev/prod builds to ...
Hello, Thank you for confirming the budget. I want to ensure we build a system that is stable, scalable, and genuinely useful for your operations rather than rushing into an overloaded implementation. Based on the project requirements, the complete solution includes multiple independent modules (AI logic layer, RFQ engine, promotions system, automation workflows, admin analytics, etc.), which are typically implemented in structured stages. Within the current budget of $500, we can confidently deliver a strong and production-ready Phase 1, which would include: • WhatsApp Business API integration • Core conversational logic & intent handling • Product search & availability via your platform APIs • Pricing response flow • Basic order / status handling • E...
Hi, I need a simple, clean website for my brand OPA! It’s Greek. The concept is a premium Greek kiosk for hotels, resorts and beach locations — a luxury guest experience.

I’m looking for an independent developer who can take full ownership of designing and building an AI-driven chatbot from the ground up. At this stage I have a clear business need for an intelligent assistant but I’m open to your recommendations on the exact feature set, tech stack, and deployment channel. Here’s what I’ll rely on you to handle: • Scoping: translate my high-level objectives into a practical bot roadmap and recommend the most suitable NLP or LLM framework (e.g., Python with LangChain, Node.js, Dialogflow, Rasa, or another option you trust). • Architecture & Build: create the conversational flows, implement the model logic, and wire up any required APIs or data sources. • Training & Fine-tuning: curate or generate sample da...
I’m rebuilding a web application whose backend currently mixes legacy PHP with newer modules. The stack centres on PHP (latest stable) and a MySQL database, and I need an experienced backend developer who can confidently step into an evolving codebase while also creating fresh, well-architected components. Here’s what I need tackled: • API development – design and implement RESTful endpoints that plug seamlessly into the existing logic and any new features we add. • Database optimisation – review schema, refactor queries, add indexes, and benchmark improvements so we can see tangible speed gains. • User authentication system – build a secure, token-based solution that fits the current login flow and is flexible enough for future SSO or OAu...
I have a Google AI Studio frontend built with Vite that is already running perfectly in the browser; what it lacks is a solid, secure connection to a MySQL database on Hostinger and a smooth path to go live. I need you to come in, design the database schema from scratch, build the API layer in either Node.js or PHP (I’m open to whichever you are strongest with), wire everything together for full CRUD capability, and then deploy the whole stack to my Hostinger account. The hosting account exists but is still in its default state, so you will also handle the basic domain + hosting setup on Hostinger before pushing the code. Security best-practices for credentials and connections are a must, as I plan to take real user data immediately after launch. Key deliverables • Database ...

I need a fully-functioning video-sharing and streaming site that captures the core YouTube experience and is ready to demo in just two weeks. The first phase is capped at US$500; deliver a rock-solid result on time and we can transition into a long-term, full-time arrangement.

I’m looking for a WordPress pro who knows Divi inside-out to give my site a complete refresh while keeping it stable and future-proof. Here’s what I need handled: • Custom design work: build a few brand-new pages, breathe fresh life into several existing ones, and fine-tune the look with clean, lightweight CSS that respects Divi’s architecture. • Plugin integration: connect the right add-ons to extend functionality without slowing the site down or breaking design consistency. • Ongoing reliability: track down and fix the nagging bugs that have crept in over time, then set up a simple maintenance routine so they don’t come back. • Seamless migration: move the entire Divi installation to its new hosting environment with zero downtime and...
I’m building DevDock into a place where developers don’t just showcase projects—they actively collaborate in real time. The core of this phase is a live coding environment that lets multiple users share and edit the same file, jump into true pair-programming sessions, and enjoy the creature comforts of modern editors such as syntax highlighting and auto-complete. Think Google Docs fluidity, but for code. Here’s what I need delivered: • A browser-based editor (Monaco, CodeMirror, or similar) wired for simultaneous multi-cursor editing. • WebSocket or WebRTC infrastructure that keeps sessions in sync with minimal latency, even when several participants are connected. • Built-in pair-programming mode—one user drives while another follows, ...

I need a lean, working web application that lets teachers publish courses and students immediately start learning. The priority is speed to a usable MVP rather than polish, so clean, well-structured code and a straightforward interface matter more than pixel-perfect design. Scope of the first release • Authentication: only email + password, securely hashed, with clear separation between teacher and student privileges. • Course workflow: – Teachers create, edit and delete courses, then add lessons that can contain plain text or embedded video. – Students browse the catalogue, enroll, and view each lesson. • Homework loop: teachers post an assignment; enrolled students submit their work; the teacher can review it inside the platform. • Notifi...
My current WordPress site is ready for a dedicated blog section. I want the blog added as a seamless part of the theme, displayed in an eye-catching grid view and styled with a colorful, vibrant palette that matches the rest of the site. The job is straightforward—something I could knock out myself in an hour or two—so code quality, attention to detail, and quick turnaround will matter most. Once I’m happy with the result, I’ll have ongoing WordPress and front-end tasks to pass along, so consider this a paid trial for a longer collaboration. Deliverable: • A fully functional blog page using WordPress’s native post system, set to grid layout and visually refined with the agreed vibrant color scheme; it should inherit all existing theme typography and...

I have already laid out the pages, uploaded test images with IPTC tags, and connected payment on my Pixpa site. What I now need is custom code that turns the layout into a smooth, sales-ready experience. Here is exactly what I am after: • Gallery enhancement Gallery setup and display to be enhanced. • Gallery search Each gallery should expose a search bar fixed at the top. A visitor types any term that exists in the images’ IPTC tags and the relevant thumbnails filter instantly without a page reload. • Multi-image selection Every thumbnail shows a small checkbox underneath it. Visitors tick as many boxes as they like, then hit a single “Add selected to cart” button—no need to open each file. • Automated tiered pricing Before the...
My current Shopify store does its job but, visually, it misses the mark. I need a skilled hand to clean things up so the shop feels modern, calm and easier to buy from. Scope of work • Layout & Design – Re-style the theme around a neutral, minimalist colour palette. You’re free to adjust any Liquid, CSS or theme settings needed, as long as the end result is light, uncluttered and consistent across every template (home, collection, product, cart). • Functionality – Tune up navigation flow, section spacing, buttons, and any micro-interactions that slow the customer down. Small scripts or Shopify app configurations are welcome where they simplify the journey. • Product Presentation – Optimise product pages for quick scanning: tidy variant sele...
I need a developer who is comfortable working within the Freshdesk Marketplace framework to build a custom app that reshapes the agent interface. The core focus is the user-interface itself—layouts, ticket view panels, contextual widgets, or any other visual element that makes day-to-day support faster and clearer for my team. Scope of work • Build a Freshdesk app (using the Freshdesk CLI, HTML5, JavaScript, and the Freshdesk Frontend API) that installs easily through the marketplace or as a private app. • Modify or replace default UI components where possible, and add new panels or tabs when required. • Ensure the finished package follows Freshworks app guidelines so it can be deployed without warnings. • Provide concise documentation: install steps, req...
I want a user-friendly Vedic astrology application that runs smoothly on web and mobile. Core modules need to calculate planetary positions using the Vedic (sidereal) system, then translate that data into: • Daily horoscope readings generated automatically from the planetary transits • Accurate birth-chart (kundali) generation with divisional charts • Compatibility (synastry) reports based on the two birth charts • Integrated numerology engine that derives and explains life-path numbers • Instant lucky-number and lucky-stone suggestions drawn from the user’s chart and the day’s transit Source code, cleanly documented, and an admin panel for managing user accounts, content text, and horoscope rulesets complete the package. Modern stacks such as...
I’m preparing to launch a new initiative called “150.000koin” and need an experienced developer to help shape the technical side of the project from the ground up. Because the concept is still being finalized, I’m looking for guidance on which platform—web, mobile, or desktop—will best fit our eventual goals, as well as practical recommendations on architecture, security, and scalability. Key objectives: • Clarify and document the core functionality that will power 150.000koin. • Propose a technology stack that balances performance, cost, and ease of maintenance. • Deliver an initial, working prototype (basic interface plus back-end logic) that demonstrates main workflows such as user registration, asset tracking, and secure transact...
I run a WordPress store powered by WooCommerce. Right now every category page sorts items alphabetically, which leaves sold-out products sitting in prime position. I’d like that changed so any item that is currently in stock automatically bubbles to the top, while the usual A-to-Z ordering is kept inside each stock group. The second part is about keeping customers in the loop. On every product that is out of stock I need a small “Notify me when available” section where visitors can leave their email address. When we later flip that specific item to “in stock” the system must trigger an email through my existing email service provider, letting only those subscribers know the product is back. Deliverables • Category-page ordering override: in-stock first,...
I need help pulling the exact wording that appears on a series of public web pages so I can repurpose it into fresh Facebook posts. I will send you a list of URLs; your task is to visit each page, copy every headline, sub-heading, call-to-action, and any punchy phrases that could spark engagement, then place them in a Google Sheet along with the page link they came from. Because the end goal is content creation for Facebook, accuracy and context matter: keep line breaks where they add meaning, omit navigation or footer clutter, and do not paraphrase—just extract the text verbatim. Deliverables • Google Sheet with one row per snippet: original wording, source URL, and character count • Quick note if a page blocks scraping or is empty If you already use tools suc...
I need a Deriv-compatible bot that will take over my forex trades completely and run a clean, rules-based trend-following strategy. The goal is full automation: from scanning currency pairs on Deriv through to order execution, position management, and trade closure, all without manual intervention. Key points to hit • Strategy logic: simple, robust trend-following rules which i will convey to you • Market scope: any forex asset, metals, crypto, indices etc. • Platform: it must run on Deriv’s DBot/Binary Bot framework or via their API, so please factor in Deriv-specific blocks, syntax, and authentication. • Risk controls: configurable lot size, max simultaneous trades, dynamic stop-loss and take-profit tied to ATR or percentage of price. • Output: the...
I’m ready to launch and need a clean, classic-looking portfolio site to showcase my work. The build should feel timeless rather than trendy, loading quickly on all devices and coded with maintainability in mind (HTML5/CSS3, vanilla JavaScript or a lightweight framework such as Bootstrap 5 is fine—whichever lets you keep the code lean). Core requirements • Visual style: Classic typography, balanced whitespace, understated colour palette. • Site type: Personal portfolio. • Pages/sections that must be live on first delivery: 1. About Me – concise bio with image and downloadable résumé slot. 2. Project Showcase – grid or carousel that I can expand easily; each project needs title, short description and external link placehold...
Proyecto: API / Sistema de búsqueda de productos en múltiples tiendas (Texto + Foto tipo Lens) Estoy buscando un desarrollador freelance con experiencia en web scraping, desarrollo de APIs y reconocimiento de productos por imagen, para crear un sistema que permita buscar un producto en múltiples tiendas online al mismo tiempo. Objetivo Desarrollar una API (o sistema backend) donde yo pueda buscar productos de dos maneras: 1) Búsqueda por texto Ej: “iPhone 15 Pro 256GB” / “Zapatillas Nike Air Force blancas” 2) Búsqueda por imagen (tipo Google Lens) Subir una foto del producto y que el sistema intente identificarlo (marca/modelo) y luego busque coincidencias en las tiendas. El sistema debe consultar automáticamente una lista...
My SaaS platform is live on FastAPI (Python) and , with OpenAI API powering several features. Everything works except the most important part: users cannot log in consistently. I’ve traced the problem to the hand-off between frontend and backend—tokens leave the browser but something breaks before FastAPI accepts them. We use JWT for all auth flows, so I need someone who knows that pattern inside out and can spot subtle communication glitches fast. Your job is to dive into the codebase, reproduce the failure, isolate the root cause, and ship a clean, secure fix. Success means a new user can sign up, receive their JWT, refresh it on schedule, and hit protected endpoints without a single 401. Deliverables • Detailed diagnosis of the communication fault between and FastAPI...
We need an experienced WordPress developer to build a custom multi-step dynamic calculator for Diesel Generators. This is NOT a basic form project.

Looking for: Strong WordPress + PHP + AJAX experience Experience building dynamic calculators Clean, scalable custom development (plugin-based preferred)
I need a clean, modern landing page that presents my service information in both English and Arabic. The page has to feel seamless for visitors switching languages, so the Arabic version must read right-to-left and mirror the layout gracefully. Core sections I want in place are a brief company overview, a clear breakdown of the services we provide, and an easy-to-find block of contact details (phone, email, and a quick inquiry form). Please build it responsive so it looks great on mobile as well as desktop, and keep load times light. A simple language toggle at the top is enough; no automatic geo-detection is required. Deliverables • Fully coded one-page site in HTML/CSS/JS (or a lightweight framework you prefer) • English copy positioned left-to-right, Arabic copy r...
I’m building a daily-play casino platform and the first release has to be a full Texas Hold’em experience that runs only on virtual chips (no real-money wagering at this stage). Your main job is to craft the complete game flow—from the lobby through hand resolution—making sure the virtual-currency economy is airtight and easy for me to tune from an admin panel. A provably fair RNG, correct hand-ranking logic, and clear table states are non-negotiable; slick, responsive visuals are strongly preferred but can be templated if your core strength is back-end logic. I’m open on the tech stack as long as it supports real-time play and scales cleanly (Unity/C#, HTML5 with Node.js + , or something comparable). Code must be well-commented and handed over with build/...
Project Description: My website works perfectly on localhost (frontend, admin panel, APIs, and payment flow), but when I deploy it on Vercel, I start getting multiple errors, especially 404 errors and payment issues. I need the live site to function exactly the same as it does on localhost without breaking any features. Tech Stack: - Frontend: React (Vite) - Backend: Serverless APIs - Database: Supabase - Payment Gateway: Razorpay + Manual UPI - Admin Panel: Custom admin dashboard - Hosting: Vercel Current Issues on Live (Vercel): - API routes returning 404 errors (e.g. /api/orders, /api/products, /api/health) - Admin panel routes showing 404 on deployed domain - Razorpay works perfectly on localhost but does NOT work on the live site - Pincode API and some serverless functions fail o...
I’m looking to turn a simple concept into a practical desktop utility aimed at adult users. The core idea is clear in my mind; what I need is an experienced developer who can translate that idea into a clean, stable application that runs on standard desktop computers. Here’s what I expect: • A lightweight, intuitive user interface that feels familiar to non-technical adults. • Smooth installation on current desktop operating systems—Windows at minimum; cross-platform support is a bonus. • Source code, compiled build, and a brief README explaining setup, dependencies, and how to extend or maintain the program. You’re free to choose the language and framework you’re most productive with (Python + PyInstaller, Electron, C#, Java—which...
ImmigrateSmart is an existing immigration-tech platform designed to deliver structured, attorney-built immigration tools and workflows. This engagement is not a greenfield build and not a long-term role. You will be responsible for implementing clearly defined modules within an existing architecture, delivering working code, documentation, and handoff—then exiting cleanly.
