About
I’m a Senior Full-Stack Engineer with over a decade of experience building high-scale consumer and enterprise products. I’ve shipped features used by millions at companies like eBay, StubHub, and Carta, and I’m currently at Drumwave — helping build a data marketplace platform aimed at democratizing how people exchange and own their data.
My strengths sit at the intersection of product thinking and technical execution. I care deeply about reliability, clean APIs, and the kind of developer experience that lets teams move fast without breaking things. Whether it’s designing a distributed system or crafting a pixel-perfect UI, I bring the same attention to craft.
Outside of work, you’ll find me with a camera somewhere remote — chasing light on mountain ridges, coastal cliffs, or city streets at dusk. The photos scattered throughout this site are mine.
