About

Eight years of frontend, most of it in fintech.

A frontend bug where I work isn't just annoying. It's money moving wrong. That's put me in the seat of setting architecture, defining standards, and owning the design system other engineers build on top of. Vue and Nuxt are home turf; React and Next are what I'm building into next.
