Design engineer
I build precise, tactile interfaces — and the systems behind them. Working at the seam of design and frontend: polished product UI and the accessible component systems underneath.
Selected work

About
I'm a design engineer who cares about the details most people only feel — visual design, interaction, accessibility, and the component systems that hold it all together.
I gravitate toward building tools. cubby-ui started as the design system I wanted to reach for on every project; SkillBundle came from scratching my own itch. I like shipping end-to-end and sweating the craft until it feels inevitable.
