What problem does it solve?
Build high-performance async APIs with FastAPI, SQLAlchemy 2.0, and Pydantic V2 to enable scalable, production-ready web services.
Core Features & Use Cases
- FastAPI 0.100+ features including Annotated types and modern dependency injection
- Async/await patterns for high-concurrency applications
- Pydantic V2 for data validation and serialization
- Automatic OpenAPI/Swagger documentation generation
- WebSocket support for real-time communication
- Background tasks and task queues for offloading work
- SQLAlchemy 2.0+ async support and migrations with Alembic
- Authentication patterns including OAuth2 with JWT, API keys
- Testing strategies and observability basics
- Deployment-readiness considerations (Docker, Uvicorn/Gunicorn)
Quick Start
Clarify goals, constraints, and required inputs, then design scalable FastAPI endpoints using async patterns and Pydantic models for production-grade APIs.
