About
I’m a product engineer. For the past nine years I’ve built mobile apps end-to-end, from fintech to early-stage marketplaces, with multiple products shipped to the App Store and Google Play. Google selected me as a Developer Expert for Flutter and Dart, which means I work directly with their engineering and developer relations teams on the framework I use most.
These days I’m focused on AI-native mobile experiences: agentic UX, on-device vision models, and the harder problem of making AI features feel native to the product rather than bolted on. I work with founders as an independent contractor (this site) and lead larger team engagements through Sorcel Technologies, the product studio I founded.
