My name is Stéphan.

I'm a software engineer in the Netherlands. Find me on Mastodon and GitHub, or you can send me email.

Whenever possible, I try to contribute back to the open-source community. The majority of this work is spare-time effort. If you appreciate any of my work, you can support me via GitHub sponsors or Ko-fi.

I'm project lead on Portier, and also take an interest in NixOS, developing unofficial tools like LazySSH, yarn-nixpkgs, yarn-plugin-nixify, and composer-plugin-nixify.

Some other fun personal projects I've done:
