SKILL.md

FastAPI async patterns for building high-performance, concurrent APIs with optimal resource usage.

Covers async route handlers, database operations (SQLAlchemy, asyncpg, Motor, Tortoise ORM), and connection pooling strategies for efficient resource management

Includes real-time communication patterns: WebSockets with authentication and broadcasting, Server-Sent Events (SSE), and streaming responses for large files or generated content

Provides concurrent request handling with asyncio.gather for parallel operations, background tasks with BackgroundTasks, and async context managers for resource cleanup

Demonstrates performance optimization techniques including caching, batch operations, debouncing, and prefetching related data to minimize latency
