    I have a fully-functional backend that already exposes clean REST/GraphQL endpoints. What I need now is a production-ready Flutter front-end that talks to those APIs and runs smoothly on both iOS and Android. Core user flows • Secure user authentication (e-mail and, if time permits, social sign-in) • Product listings pulled in real time from the existing endpoints • In-app UPC scanning with the device camera to fetch item details instantly • PDF parsing so users can upload or open a document and have key fields auto-extracted Project scope You will take the UX from Figma (or propose a lean, responsive layout if you prefer), wire it up in Flutter/Dart, handle state management, and integrate every call to the backend. Clean architecture, null-safety, ...

    I’m expanding a JavaScript-driven web platform that runs Node.js on the back-end and React on the front-end. The project needs a seasoned full-stack developer who can design new features end-to-end, refine the existing architecture, and keep our CI/CD pipeline smooth. Mastery of modern JavaScript, Node.js, Express, REST or GraphQL patterns, and state management in React is critical. Familiarity with TypeScript, MongoDB, or PostgreSQL will make collaboration even easier, though it isn’t mandatory. An intern will join at the same time, and I expect routine tasks to double as learning opportunities. The intern’s focus will be: • Assisting with coding • Testing and debugging • Documentation Your first milestone is to ship a self-contained feature...

    ...integration (UPI, cards, net-banking) into the wallet so deposits and withdrawals happen seamlessly. Alongside the player app, I also require a secure web-based admin panel. From there I should be able to: • open and close markets, post results, and adjust odds in real time • view, filter, and settle bets • monitor user balances, deposits, withdrawals, and overall revenue A clean REST or GraphQL API between app and admin is preferred so scaling is painless. Key points to keep in mind • Platform: Android only (Kotlin or Flutter is fine—whichever gets smoother performance) • Primary function: Satta Matka gameplay with real-time results • Design: traditional Matka theme—vibrant reds, earthy backgrounds, and familiar number-dr...

    ...front-end, a Node.js (Express) back-end, and a MySQL database. I already have the core idea and wireframes; what I need now is a developer who can take the project from “local prototype” to a production-ready release. Here’s the scope as I see it: • Set up the project structure, configure Vite (or similar) for the Vue layer, and establish a clean component architecture. • Build RESTful (or GraphQL, if you prefer) endpoints in Node.js, handling business logic, validation, and security best practices such as JWT or session-based auth. • Design and migrate the MySQL schema, create efficient queries, and help me plan for future scaling. • Integrate the three layers seamlessly so the front-end consumes your APIs with minimal latency. &bul...

Scope of work The system should accept images or video from web and mobile sources, parse MRZ and PDF417 zones where available, and return a clear pass / fail payload to my platform within seconds. A lightweight admin dashboard is needed for manual review, audit trails, and adjustment of match-score thresholds. Please design the backend as REST or GraphQL APIs; Python (FaceNet, InsightFace), Node, or similar proven stacks are all fine as long as they meet the accuracy target and can scale. Deliverables • Fully documented API with sample calls • Liveness detection and face-document matching model achieving ≥99 % true-positive rate at ≤0.01 % false acceptance • OCR pipeline covering passports, driver’s...

    I’m building a full-featured system for a single hotel that unifies front-desk...launch the only public role will be the Guest, who must be able to search, book, pay and receive confirmation without friction. Internal dashboards for staff and admins may sit behind the same code-base but can stay hidden from the public UI until we phase them in. Tech is your choice—Laravel, Node, Django, or a comparable modern stack—so long as you deliver clean, documented code, a REST or GraphQL API for future mobile apps, and a responsive interface that works just as well on reception tablets as it does on a guest’s phone. Acceptance criteria will be a working demo on our server, seeded with sample rooms, staff profiles and inventory items, plus hand-over of all source cod...
