Fullstack Engineer
Seoul, Korea

I'm a frontend-focused full stack engineer based in Korea, with deep experience in building scalable systems, shared UI libraries, and developer tooling for large-scale teams.

At NAVER Financial, I lead the development of core frontend infrastructure, focusing on reusability, performance, and long-term maintainability.

Outside of work, I spend time reading and writing about technology, software architecture, and the deeper questions behind how we build things. I believe thoughtful engineering is rooted in clarity, curiosity, and a strong sense of context — and I try to reflect that not only in code, but in the way I communicate and write.

I value substance over spectacle. I believe good engineering is not just about writing code, but about making thoughtful decisions that serve both users and developers over time. In the era of AI, I think engineers matter more than ever — not for how fast we ship, but for how well we understand what should be built, and why.
