Building products that matter.

I'm a founder and engineering leader with a track record of taking ambitious ideas and shipping them as real products. My superpower is working with non-technical founders — translating their vision into architecture, roadmaps, and shipping code.

After selling my last venture, Marble, to The Zebra, I joined the founding team at Ellis.ai to build AI-native infrastructure for the next generation of private credit funds. In my spare time, I advise companies navigating product, technology, and AI strategy.

My career has spanned founding a product studio, building insurance technology that served 100K+ users, scaling engineering teams to 60+, and consulting for Fortune 500 companies at Deloitte.
