• RESTful API endpoints for Todo resource (Create, Read, Update, Delete)
• SQLite database with SQLAlchemy ORM
• Database migrations with Alembic
• Health check endpoint
• Interactive API documentation (Swagger & ReDoc)

Database migrations are managed with Alembic. The initial migration is already included to set up the todos table.

Development
