Full-Stack Web App Development

This project covers building a modern, fully responsive web application from the ground up. On the front-end I want clean, component-based code in HTML, CSS, and React, with smooth behaviour on both desktop and mobile. The back-end will run on Node.js and Express and connect to a MongoDB database. Core functionality includes secure user authentication, a full CRUD API, and an admin panel so I can manage data through the browser. Three key views are required—Homepage, Dashboard, and Profile page—each wired to the API and following the same design language. While the first release does not need real-time notifications or payment processing, the architecture should keep them in mind so they can be added later without major refactoring. Well-structured, readable code with clear separation of concerns is essential. Please incorporate automated tests, address any bugs that surface during development, and assist with deployment to a production host (AWS, DigitalOcean, or similar). A brief hand-off guide documenting environment variables, build steps, and routine maintenance will complete the engagement. Acceptance criteria: • React front-end passes Lighthouse mobile scores ≥90. • All API endpoints return expected JSON and are covered by unit tests. • User signup, login, and protected routes verified with JWT. • Application deployed and reachable at a public URL with HTTPS enabled.
