What I'm looking for

I’m looking to lead end-to-end product design, build scalable design systems, and ship AI-assisted workflows—collaborating closely with Product, Engineering, and Research while keeping usability and accessibility at the center.

I’m a Senior Product Designer with 8 years of experience spearheading UX strategy and design Thinking for diverse products. I’ve defined information architecture, introduced OOUX, and used Lean UX and user research to drive clear, confident decisions.

I’ve owned end-to-end design of complex product areas—especially the content authoring experience (Editor) at Userlane—leading teams across Product, Engineering, Research & Discovery, and Customer Success. I deliver core capabilities, run continuous discovery and usability testing, and align UX patterns with design systems to improve consistency and reduce friction.

I also integrate AI-powered features into real workflows to increase efficiency, and I push for spec-driven handoff to strengthen design–engineering alignment. I’m energized by workshops, mentorship, and building accessible, scalable component libraries (with design tokens and Storybook) that make shipping faster and easier.
