About

I started builing educational software in 2010 with Code Hero, a game that reprograms itself while you play. Since then I've published 5 titles including MathBreakers, Santa's Last Stand, Bank Defense, SpaceFrogVR, and NumberSpark. As a co-founder, I've helped bring startups to funding or major growth events including StarCoach AI, VantagePoint, Havik, Humon Automation, and Primer Labs.

Between ventures, I've written music, traveled abroad, lived in Chile and Thailand, taught English in China, and started a retreat center in Puerto Rico.

Today I'm producing MathBreakers 2, a browser-based 3D platform for grades 3-8 with a built-in user generated content platform. Check it out here.
