GitHub Sponsors Profile

I'm a designer helping developers and more by creating and maintaining open source projects like Bootstrap, Code Guide, Poole, and more. I work at GitHub full-time, but dedicate my free time to maintaining open source projects to help share what I've learned over the nearly two decades of practicing design and front-end development.
