Featured Work

Pine is the center of my current design systems work.

I spent years building design systems for humans. Now I am helping design systems work for AI-assisted development too. My work connects systems, teaching, and adoption.

About

Systems that influence decisions, not just documentation.

I build systems that help teams make better product decisions at scale. My work sits at the intersection of design systems, frontend architecture, accessibility, and AI-assisted development. I care about the gap between standards and adoption. Documentation matters, but systems succeed when they influence decisions at the moment work happens.
