A minimal, production-ready Task Manager backend built with FastAPI, SQLAlchemy 2.0 (async) and SQLite.
Perfect to practice CRUD operations, validation with Pydantic, and REST API design. Auto-documented with Swagger UI.

• Python 3.11+
• FastAPI
• SQLAlchemy 2.0 (async)
• SQLite (aiosqlite)
• Pydantic v2
• Uvicorn

• CRUD for tasks (create, list with filters/pagination, get by id, update, delete)
• Filter by completion status (?completed=true|false)
• Sort by due_date then created_at
• Auto database creation on startup
• CORS enabled (adjust origins as needed)
• Swagger UI at /docs
• Async implementation (SQLAlchemy 2.0 + AsyncSession)
