bharat690/kyroo-backend — reverse-engineered prompt

I want this turned into a working Python backend for a small app called Kyroo. Use what is already started in the repo and finish wiring it up so someone can clone it, copy the env example, connect a database, run migrations, and start the server without guesswork.

Please make it feel production aware but still simple. I need a clean API structure, basic database models and persistence, a health or status route, sensible error handling, and a straightforward way to verify the database connection from the included test file. If there are missing pieces, fill them in with reasonable defaults instead of leaving stubs.

Also add clear setup instructions in the README, including how to configure environment variables, run the migrations, start the app locally, and test that the database is working. If there are places where the intended behavior is unclear, keep it minimal and practical rather than inventing a bunch of product features. You can look up current docs online if needed.
