About

I'm Yeongseon Choe — a developer who builds open-source tools and writes about Azure, Python, and backend engineering.

Most of my public work right now centers on developer experience for Azure Functions in Python: I maintain the Azure Functions Python DX Toolkit, a family of ten small, focused packages covering OpenAPI docs, request validation, structured logging, pre-deploy diagnostics, scaffolding, and AI/orchestration patterns.

I care about keeping tools small, staying close to the underlying platform, and writing examples that reflect real production needs rather than hello-world.

What you'll find here

• Projects — the open-source tools I build and maintain.
• Writing — practical notes on Azure, Python, and backend engineering.
• Azure Functions Python — my main engineering focus.
