Senior Product Ownership

At home working shoulder-to-shoulder with founders and small core engineering teams.

With 20+ years building and shipping production software, I thrive in nimble environments where engineers own features from concept through data modeling, UI implementation, and production observability. Whether designing Medusa commerce extensions, PostgreSQL schema migrations, or sub-second Core Web Vitals for multi-region storefronts, I deliver clean, tested, and maintainable software.
