Tech threads, personal essays, and a daily diary of building this site and the work behind it. New posts and thread updates land whenever I push them.
LifeOS is a React Native productivity app where every intelligent feature — scheduling, notifications, task extraction, weekly reviews — runs on a locally-quantized Gemma 4 model.
