About me
I started building Android apps in 2018 and have spent eight years on products people rely on every day, from banking and healthcare to compliance tooling for over a million commercial drivers. At Beyond ONE I lead Kotlin Multiplatform work on Virgin Mobile's apps in Colombia, Mexico and Saudi Arabia, owning payments end to end on Android and iOS, and the architecture and CI that keep weekly releases calm. At both Motive and Beyond ONE I've been release captain and on-call engineer, steering releases from code freeze to store rollout and leading the response when production breaks.
