How I streamlined backend workflows using FastAPI and async programming

For years, I relied on Django and Flask for backend work. Both are solid, but once I discovered FastAPI, I realized I could build APIs that were faster, more scalable, and cleaner to maintain. In this article, I’ll walk through how I built production-ready APIs using Python, async programming, and modern tooling. If you’ve ever wanted to make your backend fly, this one’s for you.

The article discusses the transition from using Django and Flask to FastAPI for building APIs, highlighting benefits such as type hinting, async support, and automatic documentation. Various sections delve into project structuring, defining models with Pydantic for data validation, optimizing async database connections with SQLAlchemy, and ensuring security with JWT. Additional features like background tasks for heavy jobs, caching responses with Redis, and deploying using Docker are covered, concluding with an emphasis on the efficiency and ease of coding with FastAPI.
