The entire user-facing portion of my website is already finished; what I need now is the server side that powers it. All screens, routes, and assets are coded and tested, so you’ll be working with a clear set of UI flows and sample data. Your job is to design and build a robust backend that: • Delivers JSON responses that plug straight into the current fetch/axios calls embedded in the frontend • Handles user authentication, role-based access, and standard CRUD operations for each core entity • Persists data in a production-ready SQL or NoSQL store (I’m open to your recommendation) • Deploys cleanly to a popular cloud host with environment-based configuration I’ll provide the full front-end repo, an endpoint map, and a short backlog of remaining features. In return, I’d like a Git repository with the complete backend code, migration or seed scripts, and a short README that shows me how to spin everything up locally and push to staging. Continuous deployment via GitHub Actions or similar is a plus but not mandatory. If you have a preferred tech stack, tell me why it fits this project; otherwise, propose one that balances developer velocity, scalability, and cost. Let’s get this site live.
