What I'm looking for

I’m looking for a product team that values AI-native experimentation, tight engineering collaboration, and design-system rigor—where I can frame problems, prototype fast (including in code), and iterate toward measurable user outcomes from 0-to-1.

I’m a Senior Product Designer with 6+ years designing and crafting products across healthcare, fintech, and education—ranging from enterprise surgical platforms to consumer learning experiences with 10M+ installs. I blend product discovery and problem framing with hands-on craft, partnering closely with engineering to turn complex technical systems and edge cases into interfaces people can use with confidence.

Recently, I’ve focused on AI-native product design, building and testing ideas directly in code using Claude Code and Cursor, while staying grounded in design systems and 0-to-1 product design. From rebuilding a Figma design system to cut design-to-dev handoff time by 30% and improving lead conversions by 15%, to refining real-time telestration and authentication flows for large-scale surgical platforms, I bring structure, clarity, and measurable outcomes—plus the empathy to iterate until the product truly works for users.
