Interfaces

that scale.

• 00 ABOUTABOUT
Craft, systems
and real impact.
I'm a Principal UX / Product Designer with 15+ years of experience across UX, UI, front-end and digital product. My work sits at the intersection of design, product and technology.
Good design isn't a nice-to-have. It's the difference between products that retain users and products that drive them away.
Solid technical background in HTML, CSS and JavaScript. Led WCAG audits resulting in the remediation of over 1,000 accessibility issues across multiple live systems.
