Portfolio + living design system

Hi, I'm Jeen.
I design systems that think.

Designer at the intersection of AI and design systems. My mascot — and AI agent — is a cat named Pocky.

about me

I learn by
building in public.

I'm a designer obsessed with the intersection of AI and design systems. I think design decisions should be structured, queryable, and alive — not buried in Figma files no one opens.

This portfolio is the system. Pocky — my cat-turned-AI-agent — is the interface. The work speaks for itself.
