About

I got my start on the founding team of CampusLIVE at UMass, a dorm room startup that grew into a multi-million dollar company backed by Highland Capital Partners and CRV. From there I joined Google Ventures-backed CustomMade, where I built frontend systems connecting thousands of artisans with customers seeking custom goods.

After that I spent five years as an independent consultant, working with Boston-area startups across fintech, healthcare, and beyond. In 2020 I co-founded VisualBoston, where I lead engineering. My current focus is AI-first development, building tools and workflows that fundamentally change how digital products get made.

Land-sharing for gardeners

Connects people who want to grow food with neighbors who have unused outdoor space. Landowners get a cut of the harvest or a monthly fee. Gardeners get a plot without needing a yard.
