Katie is a Staff Software Engineer on the Frontend Systems team at Etsy, where she advocates for and implements frontend best practices in collaboration with product engineers and designers. She is passionate about frontend architecture, design systems, style guides, accessibility, frontend performance, and teaching others. Katie recently co-authored the Design Systems Handbook and is participating in the Pastry Box Project, but her proudest accomplishment is creating ohshitgit.com to share her hard-won knowledge of how to get out of your git messes with a bit of humor (and a lot of swears).
