Best drawer in class since kindergarten (:
Studied traditional fine arts before moving into digital. Led design teams at frog design on enterprise application systems. Joined Yahoo!'s User Experience Design group building social and community properties. Co-founded Particle, a product foundry and consulting shop serving Google, Apple, Amazon, and Sony — acquired by Apple in 2012, where I joined Creative Services to develop its ad platform. Drove acquisition design at SolarCity (later Tesla Energy) to scale solar adoption nationwide. Then led UX at Mosaic, a leader in clean energy financing on its mission of 100% clean energy for all.
💪🏼 Today, I complement this foundation with modern AI and coding-agent workflows that accelerate exploration, reduce development friction, and enable faster, higher-fidelity product iteration.

Core features: Tempo™, a relationship-rhythm tracker that surfaces friendships going quiet; journaling with auto-tagging, full-text search, and pattern-based insights; meditation and breathwork session logging. Architecture is privacy-first — end-to-end encryption with keys in iOS Keychain, offline-first storage, and export-anytime data ownership.
