Modern API Development using FastAPI

Final Project: High-Performance Real-Time Task Management API

Design and implement a production-ready RESTful API for a Task Management System using FastAPI. The system must support user registration and authentication via OAuth2 with JWT tokens. Users should be able to create, read, update, and delete tasks. Each task must include a title, description, priority level, and completion status. The application must utilize Pydantic for request validation and response serialization, SQLAlchemy for asynchronous database interactions, and include custom exception handlers for common HTTP errors. Additionally, the project should leverage FastAPI's dependency injection system to manage database sessions and security scopes.
