Dentsply Sirona: Redesigning the Digital Front Door

The world's largest dental solutions company had a website that had grown by acquisition, not by design. I led the IA overhaul and navigation redesign that made 30,000 pages findable again.

Net32: Building the UX Practice and Design System

A dental marketplace serving 70,000+ practices had no design system and no UX process. I built both from scratch: a token-based Figma system and the practice around it. Then we used both to redesign the shopping experience.

Xbox: One Front Door for Developer Support

Game creators had no way to track the issues they reported to Xbox, and internal teams juggled disconnected tools. Workshops, design sprints, and 25 usability sessions shaped Polaris, a unified ticketing portal for both sides of the loop.

What I Do

Expertise

UX Strategy & Interaction Design

Simple experiences are the hardest to make. I generate multiple design directions early, pressure-test them with research, and align teams before engineering begins.

User Research

Usability tests, tree tests, design sprints, and interviews that surface the problems customers actually have, not the ones we assume they have. Every design decision I make traces back to evidence.

Design Systems

A well-built system is a force multiplier. I've built token-based systems from the atom up for Amazon, Fiserv, Dentsply Sirona, and Net32, enabling teams to ship faster and more consistently.

Design Leadership

I've served as principal design authority across Product and Engineering: mentoring designers, facilitating trade-off discussions, and shaping long-term platform direction.
