About

About Me

I've spent more than a decade turning ideas into products that scale. As co-founder and CTO of Zorba, I built an AI-powered real-estate marketplace from the first line of code — automating over 70% of a realtor's work and selling 150+ homes to institutional buyers like Blackstone. I pair deep technical ownership with product instinct and a bias for shipping.

Today I help companies design and ship AI-first products through consulting, workshops, and hands-on technical leadership.

Explore My Journey

Over the past decade I've gone from full-stack developer to engineering leader to founder — building web infrastructure at global scale, then an AI product from zero through Y Combinator. Each role sharpened how I architect systems that ship.
