Senior🎓
Top SchoolPete Petrash is a design engineer in San Francisco who turns experimental LLM capabilities into polished, production-ready interfaces, with 12+ years delivering product design and frontend engineering across health tech and AI startups. He has repeatedly bridged design and code as an early IC and principal at companies like Virta Health, Bicycle Health, and Plumb—shipping cross-platform patient-facing apps and core frontend abstractions that sped integration development from days to hours. At Plumb he pioneered interaction patterns for human-in-the-loop, parallel workflow invocation inside chat UIs, and at Candle anticipated present-day challenges in information verification with an ML-driven product. A relentless prototyper, Pete explores multi-agent systems, reasoning chains, and multimodal interfaces to make barely-possible AI feel inevitable. He also contributes to open-source TypeScript typings in DefinitelyTyped, reflecting hands-on fluency in both product and developer tooling.
