About

Most recently at Switch, I drive delivery for a cross-functional engineering pod while shipping production code as an individual contributor. Previously, I led front-end modernization at Dispel, guiding a 10-engineer team through a major transformation of a complex ICS/OT platform. I set the architectural direction, built the Sunnyside design system from the ground up on Radix UI with accessibility as a baseline, removed key performance bottlenecks, and overhauled the build system, cutting CI build times and enabling the team to ship faster with higher quality.
