Hey, I'm Stephen
I'm a founder, engineer, designer, and game developer in Southern California.
2022
WorkOS acquired my startup Modulz. At WorkOS I led product engineering from early PMF into high-growth scale-up and launched AuthKit, the world's best login.
2018
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.
2015
I was as an Engineering Manager at Marmot, launching ecommerce sites and eventually moving to NYC to lead the front-end engineering efforts across Newell Rubbermaid.
I also wrote my first book:
