Cole Bemis is a design engineer with 11 years of experience building polished developer-facing tools and design systems from San Francisco. He spent a significant portion of his career at GitHub—rising through design-systems roles into GitHub Next—then moved to Notion, where he continues blending research, product, and engineering. Cole is the creator of the popular open-source feather icons and has contributed to core GitHub design projects like Primer and Octicons, demonstrating strong front-end and component library expertise. His work repeatedly focuses on usable abstractions: reusable UI components, icon systems, and editor tooling that surface complex structure simply. He combines practical engineering (webpack/Babel, Vue/React) with a designer’s attention to motion and documentation, improving both developer experience and end-user UI. Beyond code, he favors building tools that help people who build things, often solving meta problems about how teams ship interfaces.
