Clarity under complexity.
I’m Tejesh, a systems-focused product designer who turns complex, safety-critical technology into clear, trustworthy, scalable experiences. I work where engineering, design, and business decisions meet- helping leadership teams turn complex technology into products people trust.
I’ve shipped automotive HMI, accessibility platforms, and physical–digital systems for Volkswagen Group and Volvo Trucks.

Accessibility Platform Service, rebuilt for a car moving at 70mph
Phone accessibility tools assume users are sitting still. I rethought them from first principles for the driver's and passenger seats, then designed one accessibility SDK for Volkswagen Group vehicles and validated it in sessions with people with disabilities against CVAA requirements.

Controls that work at 100F in Phoenix and -20F in Minnesota
I took the VNL's driving and living-space controls from modular sketches to engineering specs to vendor-ready pixels, shipping across the VNL line and Mack Trucks lineup.

Three screens, one way of reading the truck
I designed the digital cluster for glances at speed, the infotainment apps for in-cab tasks, and the MyTruck companion app — one information model, so drivers never relearn their truck between surfaces.

VNL 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 visibility 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 the four phases the truck is in.
