About

The most interesting design problems live at the infrastructure layer.

When the user is an expert and the systems are genuinely complex, clarity isn't just good design. It's the product. Thirteen years at that seam: developer tools, AI platforms, cloud infrastructure, and the interfaces engineers trust to work.

When I'm not at the keyboard, I'm building furniture or cooking something that takes longer than it should. Both teach the same lesson: knowing when something is done.

Convictions

Systems over Simplicity

The goal isn't to "simplify", it's to make dense systems legible to the experts who depend on them. Engineers don't want their tools dumbed down; they want an interface that respects their mental model. I focus on building the navigational infrastructure that turns cognitive load into creative momentum.

Design is a leadership problem

High-leverage design isn't just about the artifact; it's about the infrastructure of the org. I build the decision frameworks, feedback loops, and research cultures that allow teams to ship with predictable quality. When the system is healthy, the craft scales naturally.

Ship fast, learn fast

In complex infrastructure, speed without direction is just technical debt. I prioritize signal quality over raw velocity. A fast experiment that validates a core architectural assumption is worth more than a dozen polished features that don't move the needle.
