Task Manager API in FastAPI

I built a complete REST API for task management in FastAPI with a well-defined layered architecture (router, service, repository, DB) and a SQLAlchemy-based database. I have full CRUD testing coverage, including success and failure scenarios, an isolated test environment, and database resets. I understand the differences between HTTP code, test the API as a whole, not individual functions, and use a plan-to-implement approach. The project is ready for further expansion with pagination, validation, and JWT authorization.
