About

Hi, I'm Stephan Langeveld — a software engineer passionate about open source, developer tooling, and building things that are fast, accessible, and a pleasure to use.

I write about what I'm building and learning: performance engineering, API design, distributed systems, and the craft of software. This site is my digital garden — a place to think out loud and share what I know.

What I'm working on

Most of my work happens in the open on GitHub. I maintain a handful of open source libraries and contribute to projects I use and care about.
