Welcome

Hey, I’m Joel — an audio software developer based in Gothenburg. My path here has been a winding one: music teacher, touring playback tech, broadcast engineer at the Swedish Radio, and now mostly building game audio middleware. Along the way I picked up TypeScript, Rust, and C++, and never really stopped tinkering.

What drives me is building things that make someone’s day a little easier — whether that’s a developer-friendly library, a browser tool, or a weird experiment that just had to exist.

This site is a collection of projects I’ve worked on over the years. Some are polished, some are experimental, all were made with curiosity. Have a look around.
