Hey, I'm Stephen

I co-founded Modulz to bridge the gap between designers and developers. Along the way we created Radix, accessibility-first React components, and Stitches, a styling library with excellent DX.

I was as an Engineering Manager at Marmot and Newell Brands, launching ecommerce sites and eventually moving to NYC to lead the front-end engineering efforts across the corporation.

I also wrote my first book:
Game Development with Swift

I led engineering for a digital agency in California, producing high-profile sites for companies like Levi's, Dockers, Belk, and Genentech.
