- **Async throughout**: Mixing sync and async in FastAPI causes thread pool starvation.
Provides expert Python backend patterns for Django, FastAPI, Flask: Pydantic models, dependency injection, background tasks, exception handling, lifespan events, async programming.
Provides production patterns for async Python backends using FastAPI dependencies, SQLAlchemy 2.0 async sessions, asyncio TaskGroup, and connection pooling. Use for services, endpoints, DB sessions, or pool tuning.
