03 About

I lead teams, shape architecture, and bring on-device AI into real products without sacrificing privacy or polish.

I studied computer science before going to art school, where graphic design led me into web design and development, and from there to iOS. I still think like a designer. I've worked on campaigns for Coca-Cola and the Olympics, designed movie websites, built sites for major music artists, and made album art.
