A cross-platform mobile app targeting both iOS and Android. Within the app users must be able to: • search the entire catalog of salvaged parts by keyword, make, model, year, and VIN • post new parts for sale from the yard side, including photos, descriptions, condition, price, and inventory count • chat in real time so buyers and yards can negotiate or confirm fitment before checkout 2. A responsive web dashboard for yard owners and internal staff. The dashboard needs robust: • inventory management (batch uploads, stock alerts, status changes) • user management (role-...

I’m building a lightweight MVP that lets independent cafés run a fully automatic, card-linked loyalty programme without issuing separate cards or apps. The core of the job is a secure backend service that: • Listens to Square and SumUp webhooks / APIs, fingerprints the payment card (never the full PAN) and recognises returning customers. • Increments a visit counter and, when a customer hits the reward threshold, instantly triggers the reward logic. • Fires an SMS through Plivo to let the guest know they’ve just earned, for example, a free coffee. What I’ll look for in the finished work 1. Clean, well-documented code (language and framework are up to you as long as it’s reliable and easy to maintain). 2. Clear setup instructions a c...

I already have a draft smart contract, but it needs a careful review and a few modifications before going live. Once the code is solid, I want it deployed on Ethereum (that is my first choice, though I’m open to discussing BSC or Polygon if you feel they offer clear advantages). After deployment, the contract must be fully integrated into my website so users can interact with it through MetaMask. A smooth, reliable Web3 flow is essential—wallet connection, transaction signing, on-chain confirmations, and any UI feedback should feel seamless and secure. The job breaks down into three main parts: • Audit, adjust, and finalise the existing contract code, then compile, test, and verify it on the chosen network. • Deploy the verified contract and wire it up to the s...

I’m ready to turn my outline for a combined journal, diary, and planner into a polished product that users can open on iOS, Android, and any modern browser.

• Description We have a small Python script which needs to be put on the server-side as an API. Excluding the GUI code and comments, the script has about 750 lines. You will be given a VPS, which the API will allow downstream applications to call the engine for data comparison. We need multiple real-time endpoints for downstream applications. For testing purposes, we will set the maximum to 3 for now. Ultimately, it can be scaled to an unlimited number of real-time comparisons. I suppose we will have multiple copies of the comparison code on the same/different servers, but with three REST API endpoints. Hence, the Python script will be split into server and client-side code. As there are multiple data points to be compared with, we are thinking that the web app will first initiate...

My team needs a seasoned full-stack developer to step in as a consultant who can transfer knowledge rather than write code. I’m specifically looking for someone confident across frontend, backend, and database layers who can translate that depth into clear, structured technical training sessions.

I’m building a fitness-focused mobile app where nutritional guidance is front and center. The first release revolves around an accurate, easy-to-use calorie tracker: users should be able to search foods, add custom items, scan barcodes, and instantly see daily calories and macro breakdowns.

I’m kicking off a fresh software project and need a developer who can take the idea from rough concept to a polished, ready-to-use application. The broad goal is clear, but I’d like your help refining detailed specs, selecting the most suitable tech stack, then coding, testing, and packaging the final build.

I’m building a mobile-only app that needs a real-time text chat backend dedicated to one-on-one conversations. The goal is a lightweight, low-latency server that can authenticate users, deliver messages instantly, store chat history, and scale as the user base grows—all without the overhead of group or public room logic.

End-to-end encryption, push-notification hooks (FCM / APNs), and a RESTful or GraphQL API for ancillary data are highly desirable. Deliverables • Production-ready server code with clear setup instructions • Secure user authentication and encrypted message transport • Message persistence (Mo...

I want a full-featured social networking app built exclusively for Android.

Each of these three functions—profile creation, messaging, and feed consumption—has equal priority for the first release. You will handle everything needed to get a production-ready APK into Google Play: clean, well-documented Android code (Kotlin or Java), integration with a lightweight yet scalable backend of your choice, and a simple but modern UI that follows current Material Design guidelines. Authentication may start with email/password; social sign-in can follow in a later milestone. At hand-off I need: • Compilable source code with clear build instructions ...

Ho appena spostato il mio shop PrestaShop 1.7.5 su un server che gira con PHP 7.4 e, da quel momento, l’utilizzo quotidiano è diventato complicato: compaiono errori di visualizzazione sia nel back-office sia nel front-office e le pagine si caricano molto più lentamente del normale. Ti chiedo quindi di rendere l’intera installazione pienamente compatibile con PHP 7.4. Mi interessa che il lavoro vada oltre la semplice eliminazione degli avvisi: voglio un negozio che funzioni senza glitch grafici, con tempi di risposta nella norma e privo di fatal error in modalità debug. Utilizzo moduli standard più qualche addon di terze parti, tutti già aggiornati alla loro ultima release disponibile. Accetterò il lavoro quando: • Non si pres...

The PHP Laravel Ludo tournament website needs to be customized, details of which are given below. 1. I have 2-3 phones, all with the same Game ID login. When I play a game on one phone and upload a screenshot after the game is finished, when I try to join a new game/bet from another phone, or sometimes from the same phone, it displays "You are already in a game," even though no game is currently in progress. This prevents me from joining another game immediately, and users face significant inconvenience. 2. The game should have the option to allow players to place 2-3 bets simultaneously. For example, let's say I log in and set three separate bets of ₹100, ₹200, and ₹500. Now, if another player bets any of these amounts, they can match me on the same bet and start the gam...

I need a polished e-commerce application that works seamlessly on both iOS and Android. The storefront should showcase my full product catalog, allow quick, intuitive search, and let customers create accounts or sign in with the usual social or email options. Once users are ready to purchase, the checkout flow must connect to a secure, widely used payment gateway so transactions clear without friction. I value a clean UI, fast load times, and code that scales—preferably built with a single code-base framework such as Flutter or React Native, though I’m open to native development if you can explain the long-term advantages. Deliverables • Fully functional iOS and Android builds • Admin-side access to add, edit, or remove products and view orders • Integr...
