Solving hard problems, building durable teams.

I’m passionate about scaling engineering organizations that deliver innovative products used by millions. My work spans AI products, growth, infrastructure, machine learning, messaging, and full-stack product development.

Across Perplexity, Otter.ai, Meta, and startups, I have led organizations through rapid growth, foundational platform work, and the launch of entirely new product experiences.

From zero-to-one products to global-scale systems.

AI product and engineering

Led Otter.ai’s engineering organization as it built AI meeting agents, summarization, chat, workflows, integrations, and live agents. Grew the team from 40 to more than 135 engineers while supporting the company’s expansion beyond $100M ARR.

02

Messenger at global scale

Built and led a diversified Messenger organization of more than 120 engineers. Founded its machine learning and ranking function, led critical real-time messaging surfaces, and coordinated a cross-company privacy program involving more than 1,000 people.

Founder and hands-on builder

Co-founded Fly Labs, creating multi-device mobile video tools later acquired by Google and integrated into Google Photos. Earlier work included financial analytics at Corre Group and infrastructure automation at ServerStack.
