About

I'm a Principal Product Designer with 16+ years turning high-complexity, data-dense problems into fast, intuitive interfaces across enterprise SaaS, health tech, and fintech. I own products end to end, from discovery and rapid Figma prototyping to shipped, scalable systems, and I establish the design systems and standards that teams build on.

I specialize in clinical workflows, order management, AI-assisted tooling, and accessible, data-heavy dashboards. I've shipped for Fortune 500 companies, government agencies, and health systems, and founded three design-led software ventures.
