John Walker

Senior Product Designer

Hi, I’m John Walker.

I’m a Senior Product Designer who helps organizations transform complex products into accessible, scalable user experiences by combining product strategy, design systems, and AI-powered design-to-code workflows.

As a Web Accessibility Specialist (WAS), I bridge the gap between UX strategy, accessibility, and efficient front-end execution to deliver products with business impacts.
