I’m building a new service and need a Python-based backend that exposes a clean, well-structured RESTful API. The priority right now is user authentication—registration, login, token refresh, and secure password handling—so the code should follow best practices (hashing, HTTPS-ready, rate limiting, etc.). Here’s what I expect: • A lightweight framework such as FastAPI, Flask, or Django REST Framework—feel free to pick whichever you’re most comfortable with, as long as it stays modular and easy to scale. • Well-named endpoints returning JSON, with meaningful HTTP status codes. • JWT or OAuth2 implementation for auth, plus logout / token blacklist logic. • Unit tests and simple Postman (or similar) collection so I can verify each route quickly. • Clear README detailing setup, environment variables, and deployment steps—Docker support is a plus. If you prefer, you can architect the groundwork for CRUD and data sync so they’re easy to add later, but only the authentication portion must be fully functional for this phase. Clean, commented code and timely communication matter more to me than flashy extras. Let me know which framework you’d use and any relevant projects you’ve delivered.
