I’m an engineer in Berlin, where I work on musical instruments at Ableton.
I previously worked on emulators, operating systems, and compilers in the infosec industry. I found a memory corruption bug in LLDB once and also have a small 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 Archive, 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 for 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. I then spent the fall working at a fast food restaurant.
