Kathleen is a software engineer, designer, educator, and international conference speaker who builds design systems across engineering and product design. She creates inclusive, accessible foundations for AI-ready workflows through scalable component libraries, token-driven systems, and the tooling and documentation that help teams design, build, and ship with more clarity and consistency.

Kathleen’s a Design Tokens W3C Community Group Specification Editor. Her talks and workshops explore front-end engineering, accessibility, design systems, and modern product development, with a focus on how systems thinking and inclusive implementation improve the way teams build.

Outside of work, she is the Creative Director for the CXsisters network and the best lanterne-rouge cyclocrosser you’ll ever meet.
