Product Designer · Seeking Full-time roles
I started in fashion design and museology in Seoul, then made a sharp turn into tech when I realized the most interesting design problems live at the intersection of humans and complex systems. That shift brought me to the University of Washington for a Master's in HCI+Design.
Since then I've designed AI agent experiences at a stealth startup, shipped emotional continuity features at Lepal.ai, built AR-based onboarding at TAP3D, and architected a zero-defect design system for Project Sidewalk that mapped 12,000+ accessibility labels.
I bridge design and engineering, prototyping with Cursor AI and Claude Code, building with GSAP and React, and always grounding decisions in user research. I also explore AR and AI in the browser, from hand-tracking bloom gardens to finger-spell recognition.
