Building a design system teams can contribute to
I built components, reviewed APIs, coached contributors, and worked with design on architectural fit. Other engineers contributed components too.

10+ years of frontend engineeringCareer background
I build complex product interfaces, and the systems behind them.
I like owning a product problem from the first questions through delivery. My work spans frontend architecture, design systems, accessibility, and performance, with React and TypeScript as core tools. For my own products, I build the backends too.
Selected work
Building a customer portal around accessibility
I co-led a greenfield frontend, introduced a WCAG 2.1-guided accessibility specification, and checked keyboard navigation myself.
Profiling the Layers panel in a design tool
I did the DOM and CSS work in a team rebuild of the Layers panel, guided by browser profiling. Another developer handled JavaScript; we shared constraints across the two parts.
Writing
Standardize what ships, not the workflow
My approach to shared engineering standards: keep production boundaries explicit, and give people room to choose how they work.
