Selected work

Summary. Software product builder, 20 years.

I take products from idea to shipped and own the whole thing: product definition, design, and engineering. You get one accountable owner from first decision to launch. I’ve built and led work at Twitch, Hipmunk, Bebo, and charity: water, founded App Store apps Apple has featured, and run my own studio, Nerd Tower, handling the full technical side for founders, small teams, and selective private clients: deciding what to build, designing how it works, shipping it, and keeping it running. Native iOS and full-stack web.

Agentic engineering is core to how I work: I build with AI coding agents day to day, and I run local LLMs on my own hardware for private, self-hosted tooling when work needs to stay in-house. I treat sensitive work as confidential.

Building great products since 2005 for companies including Sonato, Twitch, Hipmunk, Bebo, charity: water, Founder Dating, and more.
