About

Currently building independently — software, hardware, and interactive systems. Systems-minded engineering leader and builder focused on clarity, composability, and performance. I built teams and platforms that make large-scale AI clean to reason about and evolve. Founded and scaled Pinterest’s ML Platform, unifying infrastructure and teams across the company to power large-scale recommendation, foundation, and generative models.
