I translate regulatory, operational and safety constraints into experiences people can understand and use — in vehicles, on connected devices, and in the intelligent systems that act on their behalf.

PRINCIPLES

How I design for trust.

In a vehicle, on a device, or anywhere
software acts on someone's behalf.

01

Constraints are the brief.

Regulations and safety needs aren’t obstacles — they’re the clearest direction a designer can get.

Hours of Service · ELD · ADAS

03

Earn trust in automation.

Show what the system is doing, ask before acting, and make mistakes easy to recover from.

ADAS alert escalation · voice consent & error
recovery

02

Design for the moment of use.

Ride along, sit in, watch closely. The best insights come from the cab, not the conference room.

Field rides · dispatch shadowing · concept-
vehicle journeys

04

Scale it, then ship it.

Design once, work everywhere, and hand engineering specs they can build from.

Android Automotive OS · OEM & Tier 1 partners ·production specs

Calm handover

Situational awareness, contextual assistance and alert fatigue — when, where and how a vehicle should ask for a driver's attention, and when it shouldn't.

VOICE + AI · EXTENDS WORK 02

Consent first voice

An independent extension of my Infiniti QX Inspiration work, built through AI-assisted prototyping: four dialogue iterations, intents and slots, consent before saving preferences, and error recovery.
