I build software end to end and stay for the boring part: keeping it alive.

01 / About

Twelve years writing code, from firmware for network hardware to product design systems. I have been the whole team on a startup and one engineer among many in a scale-up, and I am useful in both.

I like the parts most people skip. Naming things properly. Deleting code. The migration nobody wants to own. Design systems, because a good one makes everyone around you faster.

Between 2020 and 2023 I streamed on Twitch and YouTube, explaining things to strangers, which turns out to be the same skill as engineering with other people.
