About
Howdy — I'm Derek Hatfield, a design system leader based in Austin, TX.
Currently a Design Systems Manager at Dexcom, where I build the infrastructure that complex organizations and growing teams need to scale. Previously, I led the native design system and AppX redesign at USAA, and built General Motors Manufacturing IT's first design system.
The through-line of my career: I keep ending up as the person who builds the system nobody asked for but everybody needed — pitching it, shipping it, and running the governance that keeps it alive.
The Path Here
I started in brand and advertising — creating ads for Coca-Cola, McDonald's, Heineken, Gibson — where I learned that craft is non-negotiable and deadlines don't care. Mobile product design pulled me into UX; enterprise scale pulled me into systems. At GM I built Manufacturing IT's first design system and shipped products on it; at USAA I helped found the native design systems team for 14 million members. Today I manage the design system at Dexcom, Inc., where a 2-person team and I run the tokens, components, and governance behind 7 products. Every stop taught the same lesson at bigger scale: consistency isn't a style choice, it's an operating model.
How I Work
Systems are products, and their users are teams. A design system succeeds when using it is easier than not using it — which means documentation developers can copy from, components that earn their place by shipping, and adoption you measure instead of assume.
Craftsmanship at every altitude. I care about the 4px that's wrong in a button as much as the contribution model that's wrong in an org. The small stuff and the structural stuff fail the same way: quietly, then everywhere.
Sell the unglamorous work. The hardest part of every system I've built wasn't the design — it was winning the mandate, the budget, and the trust to build infrastructure instead of features. I've gotten good at that argument.
