Description:
Master FastAPI from scratch and learn how to build, secure, test, and deploy production-grade AI backends. This complete course covers everything an AI engineer needs to go from building LLM apps to shipping them — REST API design, Pydantic models, dependency injection, JWT auth, rate limiting, PostgreSQL, vector databases, background tasks, Docker, and cloud deployment.
You will build two real projects: a RAG API for podcast transcripts and a Text2SQL agentic API — both production-ready and fully deployable.
What you will learn:
? FastAPI fundamentals — async, routing, type hints, OpenAPI docs
? Request/response design with Pydantic
? Dependency injection, settings, and lifespan patterns
? API key and JWT authentication
? Rate limiting and abuse protection
? Automated testing with pytest and TestClient
? State management with PostgreSQL and Qdrant
? Background tasks and job patterns
? Docker containerization and cloud deployment
? Two complete AI backend projects
