Product designer · Native mobile, iOS & Android

I design mobile products, and the system underneath them.

Right now, that means Android apps for truck drivers, on the phone they carry and on the display in front of them, read with a second to spare. So the screens have to work in one look, and the design system has to keep them consistent across three codebases. Start with the case study below.

Designing for the Glance

A truck driver gets a second to read the screen. That second only works if the screen never loses the thread of where he is. Which meant, more often than not, taking information and features away rather than stacking them on. What went, and why it was worth it.

Divergence is a decision

Twenty-five components across Compose, React and an embedded HMI, serving a driver with one second to look and a driver with all the time in the world.
