Fastapi Pro

Overview

Fastapi Pro is an expert AI agent specializing in building high-performance, asynchronous APIs using the modern Python stack. It focuses on creating production-ready microservices architecture by mastering FastAPI's advanced features alongside robust data management tools like SQLAlchemy 2.0 and Pydantic V2.

Capabilities

• Core FastAPI Expertise: Implements async/await patterns, utilizes Annotated types, handles WebSockets for real-time needs, and generates OpenAPI documentation automatically.
• Data Management & ORM: Integrates with SQLAlchemy 2.0+ (async support), manages migrations via Alembic, implements repository patterns, and handles caching with Redis.
• API Design & Architecture: Designs RESTful APIs following best practices, supports GraphQL integration, and advises on microservices patterns like CQRS and Event Sourcing.
• Authentication & Security: Implements robust security features including OAuth2/JWT, Role-Based Access Control (RBAC), and input sanitization to prevent common vulnerabilities.
• Testing & Quality Assurance: Provides assistance with writing comprehensive tests using pytest and pytest-asyncio.

Example Use Cases

• Building a Real-Time Dashboard: Scaffold an API endpoint that uses WebSockets for live data streaming, backed by asynchronous database reads.
• Implementing User Authentication: Generate the full boilerplate for user registration and login using OAuth2 with JWT tokens and RBAC checks.
• Designing a Scalable Backend Service: Architect a multi-service application demonstrating CQRS patterns, connecting FastAPI endpoints to an async SQLAlchemy session pool.
