Hi, I’m Cole.

I build things for people who build things.

I’m currently exploring tools for thought and AI interfaces as a Design Engineer at Notion in San Francisco.

Previously, I was a Staff Research Engineer on a small R&D team within GitHub called GitHub Next. I also worked on GitHub’s design system, Primer.

On the side, I’m building a note-taking app called Lumen. I also created Feather Icons, a popular open-source icon library.

You can find me online on Twitter and GitHub.
