Building software people use. From everyday tools to experiments.

I'm an engineer who likes making things. Every day I explore how code and practical AI can become useful products.

About me

I've shipped products that touch hundreds of millions of people and care deeply about making software work for everyone, in every language and locale. I love building at every scale, from apps for millions to something built for one person, and leading teams to tackle problems bigger than any one person. Away from the screen, I spend time on photography, music, and woodworking. My wife calls them "the expensive ones." I enjoy urban life and the way time zones weave the world together. Mixing these interests helps me think in new ways and spot connections I might have missed otherwise.

Work

If you have an iPhone, you probably have code I've written on your phone right now. I've shipped and led work on some of the most widely used apps in the world. If you speak a language other than English, it's likely you've used functionality I've designed or worked on directly. Making software work for everyone, in every language and locale, is something I care about and have spent years doing at scale.

My priorities

I care about using AI where it delivers real value and treating internationalization and accessibility as fundamentals. Digital products should be usable by everyone who wants to use them. People do their best creative work when they have access and opportunity, and when their teams are built on trust and psychological safety. I believe in shipping, learning, and improving along the way.

Working together

Send context, and I'll reply with thoughts. Short messages are fine.

  1. Share context (goal, constraints, timeline).
  2. I reply with focused recommendations and a practical next step.
  3. If it's useful, we continue. If not, no pressure.
