Hi, I'm Johann.
I work on AI Security in Google Chrome — mostly the parts that decide what a website is allowed to do. Before that I did a lot of things that made me better at this one.
I gave conference talks for a few years and then stopped, which I have no regrets about. Writing turned out to suit me better: slower, quieter, and you can fix it afterwards.
Outside of that: long walks, mechanical keyboards I claim are for ergonomics, and an ongoing project to keep my notes in plain text forever.
Elsewhere
Places I've lived
Four so far, in this order. Hover a dot for the why.
Berkeley Berlin Lisbon Boston Area
Berkeley 2016–17
A year in California, on an exchange. Mostly fog and good burritos.
Berlin 2017–22
Where I started working on browsers, and where most of my people still are.
Lisbon 2022–23
A stretch of working from a much warmer flat.
Boston Area now
Massachusetts. Close enough to the water, cold enough to stay inside and write.
