About me
I’ve spent more than 20 years building products and the teams behind them, working across design, engineering, architecture, and technology leadership.
My best work starts with a difficult problem, not a finished spec. I help teams decide what to build, make the right technical calls early, and carry it through production.
Founder & CTO of Immutable. Based in Milwaukee, Wisconsin.
