I'm Timothy Serem, an Android engineer in Nairobi. For 5+ years I've built for people who work far from a signal — pastoralists, vets, growers — with data that stays encrypted on the device, maps that render offline, and sync that survives a dead network. Lately I run that work with AI agents in the loop: a modularization we'd scoped in months landed in weeks.
