I’m an artist & engineer in Berlin. I work on digital musical instruments at Ableton and am a developer on the team that created Ableton Move. I also live stream OS development every Sunday @ 10:00 ET.

Previously, I worked on emulators, operating systems, and malware R&D in the infosec industry. I found a memory corruption bug in LLDB once and also have a tiny patch in the Linux kernel.

I write about topics like computer science, creativity, life, and career, with this site being somewhere between a personal blog, journal, and research archive. Check out the the Writing, as well as my Twitter, Youtube, and Podcast.

I am currently ten years into my journey towards becoming a pro systems programmer.

Fun Facts

I produce music. (And have been since 2010 — longer than I’ve been programming). I used to make metal, but now make wave and did a one-off emo EP once.

In 2020, I took a gap year and created Timestamps, a workflow product for DJs, which I grew to a humble $50 MRR before making it free. It’s processed 12,000+ project files since 2020, and gets a few uploads every day.

I then spent the fall working at a fast food restaurant.
