About
Seven years in, I still think the best compliment a product can get is “I did not have to think about it”. I work on the unglamorous middle of a product — the flows, the empty states, the error copy — and then put something on top worth looking at.
Most of my work is with small teams shipping their first serious release: marketplaces, tools for small businesses, and the occasional stubborn internal dashboard nobody wanted to own.
What I do
-
Product design
End-to-end: research, flows, interface, and the design system that keeps it from drifting six months later.
-
Illustration
Editorial spots, onboarding sets, and brand characters that survive being shrunk to 24 pixels.
-
Design audits
A hard look at what you already shipped, written up as a ranked list you can actually work through.
