Proof of work
These projects highlight my production work as an HMI/UX/Interaction designer over the last 8 years in Automotive. The challenges addressed include reducing cognitive load in safety-critical systems, designing for accessibility at scale, and unifying experiences across brands. These issues, and my approach to solving them, are relevant beyond this industry.
I am open to applying my experience to new challenges and domains.

Accessibility Platform Service for Volkswagen brand vehicles
Mobile accessibility tools like VoiceOver and screen readers were never meant for a car moving at 70 mph. I helped rethink them from first principles for the driver’s seat and passenger, then designed one SDK that now ships across four brands and 20 million vehicles.

Control Modules for Driving and Living space in Truck
Every control had to work perfectly while driving and in the living environment of a cab , in 110°F Phoenix heat or a –20°F Minnesota night. I took the system from modular sketches to engineering specs to vendor-ready pixels, shipping across Volvo and Mack.

New Digital Ecosystem - Cluster, Infotainment & Companion App
Three screens, one way of reading the truck. I designed the digital cluster for glances at speed, infotainment apps for in-cab tasks, and the MyTruck companion app. That continuity means drivers never have to relearn their truck between surfaces, across 100+ features on Volvo’s award-winning flagship.

Volvo Truck Iconography
A brand mark for the truck itself. Built on a keyline grid, not drawn freehand, I designed VNL’s front and side symbols with corporate-logo discipline and shipped them unchanged across hardware, software, the app, and marketing for Volvo, and as a benchmark for Mack Trucks.

Digital Co-pilot for Job
Ready-mix drivers ran a full load-to-pour cycle using outside switches, hand signals, and a clipboard, with almost no view of it from the cab. Starting from field research on a job no one had mapped, I architected an in-cab app that always knows which of four phases the truck is in.
