I’m building a modern, data-driven KPI dashboard that executives can open on any device and instantly understand performance trends. The front end should be crafted with clean, component-based HTML, CSS and JavaScript—React is strongly preferred for its state management and speed—while the back end can run on Node.js, PHP or Python. Data will live in either MySQL or MongoDB, whichever you are most comfortable optimizing. Functionality in scope: • Secure login with two distinct roles: an Admin who manages every data point and a Standard User who can view and interact with metrics. • A polished admin panel where the Admin imports, edits and deletes KPI records. • Rich visualisation powered by bar, line, pie and area charts. Users must be able to filter o...

My React-based appointment platform is almost ready to ship, but two stubborn issues in the scheduling logic are blocking release: • The time-slot generator sometimes shows options that should be unavailable. • When a user hits “Book,” the request hangs far longer than it should. I need a developer who can dive straight into the existing React frontend (hooks and context), trace the slot-generation flow through to the scheduling API, and deliver a clean, well-tested patch. You’ll verify that only legitimate slots appear under every timezone/working-hours scenario and profile the booking call so the confirmation returns promptly. Deliverables (acceptance criteria) 1. Updated logic that always publishes correct, conflict-free time slots. 2. Booking operat...

I am building Meet-sphere, a browser-based video calling platform geared toward friends and family. You can preview the current proof-of-concept here: The core is already in place—ReactJS on the front end, an Express/NodeJS API backed by MongoDB, and peer connections over WebRTC managed through with token-based authentication. I now want to move from demo to production quality by adding: • Screen sharing that works smoothly on Chrome, Firefox, and Safari • Multi-user conferences (3–6 participants in a room without noticeable lag) • An integrated text chat pane, delivered over the existing socket layer and persisted to MongoDB for reloads The codebase is modern React (hooks, Context, Vite), and the server runs on Express with JWT auth. You’ll have...

I’m building a new white-label iGaming suite that bundles an online casino and a full-featured sportsbook into a single, scalable platform. The project covers everything from the real-time odds engine to the front-end lobby, and I need a senior full-stack developer who can own the build end-to-end. The back end must be modular—micro-service friendly, containerised, and ready to plug in third-party game providers, odds feeds, KYC tools, and multiple payment gateways. A modern stack such as Node.js or Go for the services, TypeScript/React (or similar) for the client, and a cloud environment like AWS or GCP with Docker/Kubernetes for orchestration is preferred, but I’m open to your proven alternatives if they shorten time-to-market without sacrificing reliability. On the f...
