API RESTful Jobs

I’m looking for someone based in Kollam, Kerala who can jump straight into an existing React web application and keep the momentum going. The core codebase is already live, but new screens, tweaks to component logic, and a round of performance fixes are pending. You’ll be working directly with me; I’ll walk you through the current repository, explain the backlog in Git, and hand over access to our staging server so you can ship updates quickly. Because the project is already in production, I need clean, modular code, familiarity with modern React hooks, and an eye for maintaining consistency with our current styling approach (we’re on CSS-in-JS). A solid grasp of RESTful APIs and version control in Git is a must, as those are central to the workflow here. Delivera...

I need a full-stack developer to build a website in Node.js that cleanly presents three core areas—business listings, a blog section, and a product showcase—supported by a secure admin panel. The admin area must let me create, update, and archive content for each of those modules using a straightforward email-and-password login flow. Visual direction is modern and minimalist: lots of white space, clear typography, subtle accents, and a layout that feels snappy on both desktop and mobile. I’m happy for you to pick the most suitable Node.js framework (Express, Nest, Next, etc.) and database, as long as the code is modular and easy for another developer to pick up later on. Key deliverables: • Responsive public site with the three content sections wired to dynam...

I’m looking for a developer who can build a social-networking web application from scratch. The core idea is to let users create profiles, post updates, follow friends, and exchange private messages—nothing overly complex at first, but the foundations should be solid enough to grow. Here’s what I need delivered: • A responsive front end (React, Vue, or similar) with clean, modern UI components for feed, profile, and messaging. • A secure back end (Node.js, Django, or comparable framework) that exposes RESTful endpoints and handles authentication, user relationships, and real-time notifications. • A lightweight admin panel to moderate content and manage users. • Deployment scripts or documentation for hosting on a mainstream cloud platform (AWS, ...

I have an enterprise decision-analysis product on the roadmap and I need a senior-level Microsoft Azure engineer who is comfortable taking full ownership of the Azure development. The core requirement is an unsupervised machine-learning pipeline—deployed and managed in Azure—that can ingest raw data, uncover patterns autonomously, and feed those insights into the application’s decision engine. Here is what I have in mind: data lands in an Azure Data Lake, is processed through Azure Databricks or Synapse, and the unsupervised models (clustering and anomaly-surfacing techniques are likely candidates) are trained and versioned in Azure Machine Learning. Model output then needs to be exposed via a RESTful endpoint, secured with Azure AD, and consumed by the front-end service...

I need a lean, front-end MVP built in React that lets patients do three things with ease: keep track of their own medical records, book appointments, and handle billing or invoicing. The goal is to demo these flows end-to-end so stakeholders can validate usability before we invest in a full-scale build. Core scope • Patient records: create, view, update, and delete basic demographics, visit summaries, and file attachments (use local or mocked API storage—no HIPAA data involved at this stage). • Appointment scheduling: calendar view with available slots, confirmation screen, and simple reschedule / cancel actions. • Billing & invoicing: list of outstanding invoices, card or PayPal mock checkout, and downloadable PDF receipt. Tech & workflow React (hook...

I already have the hosting and a fresh Laravel 10 install; what I need now is a complete directory system that can scale to multiple countries from day one. The core data type is Businesses, and every business needs a rich profile page that owners can claim, edit, and track through a clean dashboard, while I still retain full administrator control from a separate super-admin panel. Key features that must be working before hand-off: • User reviews & 1-to-5 star ratings, tied to authenticated accounts • Full business profile with logo, gallery, opening hours, map, and custom fields I can add from the back-office • Fast search with filter by category, country, city, and rating, plus a “near me” option using geolocation Because both owners and administrat...

My Laravel web application is already 80 % built and running on a staging server. I now need a seasoned Laravel developer to step in, review what’s there, and drive it over the finish line for production release. You’ll get full Git access, an existing Trello board with open tickets, and my direct support whenever something needs clarification. The remaining work spans tightening up a few controllers, polishing Blade views, resolving edge-case bugs, making sure all Eloquent relationships are solid, and packaging the whole thing for a clean deployment (migrations, seeders, env configs). If you see any quick-win performance tweaks or security gaps, feel free to tackle those as well. Acceptance criteria • Every outstanding ticket on Trello marked “Done” and me...

We're building a high-velocity venture studio and are looking for a vibe-code-affine full-stack developer who can take a functional UI prototype and turn it into a launch-ready MVP—fast, clean, and production-safe. Our workflow: We deliver a clear concept + functional UI prototype (, no DB/auth yet) You take it to launch readiness in ~1 work day (sometimes 2 for slightly larger scopes) Stack and guardrails are predefined to minimize friction You’re encouraged to vibe code, but you must know when to slow down and do things correctly This is not greenfield architecture work and not pixel-pushing. It’s about execution speed with technical judgment. Typical Scope (per project) You will: Add Supabase backend (Postgres, auth, RLS) Implement magic-link auth (OAuth optiona...

I’m building a Spring-based service router and need robust CSRF protection on all API endpoints. The idea is to leverage Public Key Infrastructure so that every incoming request carries a verifiable, signed token before it reaches any controller logic. Here’s the core of what I’m after: • A Spring Security configuration (Boot-compatible) that intercepts every request—GET, POST, anything—and checks a PKI-backed CSRF token. • A lightweight way for upstream services or clients to obtain and refresh that token; we can refine the flow together once you see my current architecture diagrams. • Server-side validation that ties the token to the session (or an equivalent stateless approach) so replay attacks are blocked. • Clean, readable ...

I am building a fully-featured social networking platform from the ground up and need a developer who can own both the server-side and front-end work. The stack is set: C# ASP.NET (Core preferred) powered by an MS-SQL database. Scope of work You’ll start by architecting the database, spinning up the ASP.NET project, and exposing a clean, well-documented REST (or GraphQL, if you prefer) API. Identity-based authentication, role management, and token-based security need to be wired in from day one. Key features I must see at launch: • Messaging system (asynchronous and real-time) • News feed with post, comment, like, and share capabilities • Private chat using SignalR or an equivalent WebSocket solution • Meeting scheduling module that lets users create, ...

We’re looking for an experienced automation specialist to build fully automated, low-cost social media marketing and content workflows across multiple brands.

I’m building an internal business tool for our clients and customers, powered by a Node.js back-end and a React front-end. I’ve already mapped out the core architecture and now need a developer who can turn that plan into a clean, production-ready application. Core features we must deliver: • User authentication – secure sign-up, log-in, and role-based access • Data visualization – interactive charts/graphs that pull from our REST endpoints • File upload & download – reliable handling of documents up to 50 MB, with progress indicators The back-end will expose a RESTful API in Node.js (Express is fine), connect to a PostgreSQL database, and include JWT-based auth plus basic rate limiting. On the front-end, React (hooks, functional compo...

I need a developer who knows WordPress, Paid Memberships Pro, and Verotel FlexPay inside-out to build a bespoke PMPro payment gateway. The goal is seamless subscription management: members must be able to sign up through Verotel, have their memberships renew automatically, and lose or regain access the moment Verotel notifies us of a change. Core behaviour • Create new subscriptions and capture initial payments through Verotel’s FlexPay API. • Process automatic renewals without user intervention. • Listen for and verify incoming HTTPS webhooks (Verotel “postbacks”) for: – rebill success – rebill failed / payment declined after retries – subscription canceled – chargeback or refund • Translate every webho...

I maintain a legacy desktop program written in Pascal and now need it re-imagined as a browser-based application. The goal is to keep every current feature intact while exposing the underlying logic through modern APIs, then presenting it in a clean, responsive web interface. Here’s the workflow I have in mind: • Re-factor or wrap the existing Pascal code so its core routines are callable from HTTP/REST endpoints. • Build the web front-end (framework is flexible; React, Vue, Angular or even a light vanilla stack are all acceptable) that consumes those endpoints and mirrors the original UI/UX. • Package the finished solution with clear deployment scripts and concise technical documentation so it can be dropped onto a standard Linux server. Key points you’ll...

Looking react developer to design and development of a modern, responsive, and high-performance web application using React.js The work will involve UI development, API integration, and performance optimization. The website will communicate with backend services through RESTful APIs to fetch and manage dynamic data.

I need a Hostel Management System developed using the MERN stack (MongoDB – Database, Express – Backend Framework, React – Frontend, Node.js – Runtime) with secure role-based authentication for Admin, Warden, and Students, enabling management of student records, room allocation and vacancy tracking, fee structure and payment status, attendance, complaints, and notices, featuring a responsive UI, clean and scalable code architecture, and proper API integration

I need a single, cohesive web application that lets our staff handle day-to-day school operations without jumping between spreadsheets. The platform must run entirely in the browser yet feel as responsive as a desktop app, so a modern stack and clean UI are essential. Core scope • Student Information System – searchable student profiles, class assignments, contact history, document uploads. • Attendance Management – daily roll calls, bulk uploads, real-time status changes, attendance reports. • Fee Management – fee plans, automated billing, payment tracking, receipt generation, exports. Role-based access Admin, Teacher and Student dashboards must surface only the data and actions relevant to each role, with a secure login, password reset and per...

I’m rolling out email-based one-time-password verification for both my iOS and Android apps and I want the messaging to run through Amazon Simple Email Service. I don’t yet have an SES account, so the job starts with creating and configuring one from scratch—moving it out of the sandbox, verifying the sending domain or address, and generating production-ready SMTP/API credentials. Once the service is live, I need the full OTP flow implemented: generating secure codes on the backend, sending them through SES, and exposing a clean endpoint that the mobile apps can hit to request and validate the codes. The final result should allow a user to enter their email, receive the OTP within seconds, and use it to confirm their account—all with deliverability and rate-limitin...

Overview I am seeking an experienced software developer to deliver Phase 1 of a research-grade macOS-native options analytics application. This phase is not about UI polish or trading automation. The goal is to de-risk the hardest parts early: Schwab API data integrity, trade/position grouping, and an analytics-ready architecture that can support advanced volatility, Greeks, and Monte Carlo analysis in later phases. This is a data and analytics foundation build, not a full application yet. Phase 1 Scope (Fixed & Explicit) In Scope 1. Native macOS application skeleton (Python preferred; alternatives must be justified) 2. Charles Schwab / thinkorswim Trader API integration A. Sandbox + production access B. Historical trades C. Open/closed positions D. Options chains, prices, IV...

I need a lightweight API scaffolded with Vite and deployable straight to Vercel’s serverless environment. Each route must live in its own folder so that the folder name maps directly to the public path, and the JavaScript file inside that folder answers the request with either a GET or POST handler. Core features • User authentication: issue and validate tokens so protected endpoints are only accessible to logged-in users. • Data submission and retrieval: accept JSON payloads via POST, return JSON on GET. I’m flexible on the underlying database—please propose the option you feel fits best with Vercel’s edge-friendly architecture. Regarding this website which belongs to Deliverables 1. Vite project with the folder-based routing convention in pl...

I’m putting together the first-release MVP for a web-based marketplace that matches service providers with customers. The scope is lean, but quality can’t slip: the front-end has to feel effortless, the architecture needs to stay clean for future iterations, and the backend logic must be dependable from day one. My immediate priority is User Experience, so every screen—desktop and mobile—should guide newcomers smoothly from sign-up to booking and payment. At the same time, the codebase should be modular enough that adding new verticals or a mobile app later will be straightforward. I’m happy to collaborate with either a tight two-to-three-person crew or solo specialists who clearly state which slice of the build they’ll own (e.g., React UI, Node/Expres...

I’m midway through building a Laravel-based application and need another set of expert hands on the back-end. The core framework is already in place; now I want to accelerate feature development, tighten up existing code, and make sure everything scales cleanly. You and I will collaborate through GitHub feature branches and pull requests. Typical tasks will include creating or refactoring RESTful APIs, improving Eloquent relationships, optimising queries, adding queue jobs, and firming up middleware for role-based access. Clean, PSR-12–compliant PHP and meaningful PHPUnit coverage matter to me just as much as shipping fast. You should be comfortable working autonomously, yet open to regular code reviews and brainstorming sessions on Slack or Zoom. If you have experience integ...

I work with developers who have built real, client-facing software products or platforms in specific geographies. Many of you have already validated features, adoption, and business models in your markets.
