Background
About
I'm a founder, product engineer, and educator based in New York City. I build software that helps people learn, grow, and ship faster.
I founded Flatiron School, where I taught 10,000+ students to code and built Learn.co, the LMS that inspired GitHub Codespaces. Along the way, I co-founded Kode With Klossy with Karlie Kloss.
Currently, I'm building AI-powered tools and exploring how agents can transform developer workflows. I believe in shipping fast, solving real problems, and using AI to amplify what's possible.
I'm legit, I've been in all these publications (and more)!
