Portfolio
I take products from idea to launch and own the whole thing: product definition, design, and engineering. Twenty years of native iOS and full-stack web, for companies like Twitch, Hipmunk, Bebo, and charity: water, plus my own App Store apps. Most recently I spent four years as Sonato’s sole iOS developer, through 2026. These days I build with AI coding agents as a daily driver.
