About

Professional summary

I am a senior product designer and design systems specialist with 23 years of experience, including ten years focused on regulated and enterprise products. I build scalable systems that connect product, brand, engineering, and governance.

I have built design systems from scratch for organizations including Avant, Blue Cross Blue Shield, TransUnion, and SurePeople. My work spans component libraries, token architecture, documentation, accessibility guidance, release processes, and developer handoff.

I structure design tokens across raw values, intent, and component layers, then work with engineering to ensure the component library is practical and production-ready. I design for web, iOS, Android, and complex enterprise workflows.

My background includes product design, UX/UI, visual design, brand direction, research, usability testing, and design leadership. I have worked with healthcare, fintech, insurance, retail, telecommunications, and other enterprise teams.

I use AI-assisted tools including Claude Code and Figma Make in my daily workflow while keeping design judgment, quality decisions, and final execution human-led. I also create live documentation sites and design-system-as-code experiences that make systems easier to adopt and maintain.
