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.

At Kajabi

Design system knowledge where product work happens.

I build design systems for product teams, create AI workflows that help those systems scale, and teach web design through a learning platform built from my LSU curriculum. At Kajabi, I help evolve Pine, a multi-platform design system used by 40+ engineers across 6 product teams.

Featured Writing

Design systems, AI-assisted development, and frontend quality.

Recent essays on how system knowledge, governance, and standards need to show up inside modern product development workflows.

Teaching

Web foundations, accessibility, and systems thinking.

I also teach web design and frontend development at Louisiana State University, where I help students build foundations in HTML, CSS, JavaScript, accessibility, UX, responsive design, and systems thinking.

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.
