About
I make the hard calls visible: what we build first, what we cut,
and why.
01
Systems, not one-off screens
Co-created Qu's first Global Design System, adopted by Enterprise Intelligence, Notify and Qu Order Management, built Volt at EOS, and started Qu's design reviews from zero.
02
Close to the people on the floor
I start with operators, support teams and enterprise customers before I open Figma.
03
Scoped with engineering, not handed to them
Hard constraints like offline mode, legacy data and rush hour speed shape the design from day one. Lately I prototype straight from PRDs with Claude.

Signage taught me to design for people in a hurry, reading from across the room. I still design that way: clear before clever, and when it fits, a little joy.
