About
I'm a mobile engineer who has spent the last decade shipping Android at consumer scale. Most recently that was a social app serving 3M daily active users, 300M daily messages and over 50M downloads.
My work tends to sit where performance meets architecture: reworking rendering paths, replacing legacy subsystems, and making untestable code testable. I care about the numbers that come out the other side.
Outside of Android I work with iOS, Flutter and React, enough to build and ship my own side projects end to end.
