- User research & journey design
- Business-driven design decisions



I care about doing things right, not just fast. Before I open Figma, I want to know what the organization actually needs, and whether the problem is worth solving at all.
I joined a Korean healthcare startup as its third team member, back when it was still an MVP. I stayed through Series B, grew into Design Lead, and became a shareholder along the way. The work split between our own products and large‑scale systems built with hospital partners. It taught me that the best work happens when people think together. I can work alone, but I do my best work on a team that pushes back.
If anything, I'm a generalist, and in the AI era that has become my edge. I can take an idea from 0 to 1 on my own, prototyping in code, while keeping the parts that should stay human: strategy, ideation, and deciding what to build first.
