/about
I'm a software engineer based in Seoul, South Korea.
Born in Seoul, raised in Shanghai. I care about the systems under the surface — how they scale, how they stay up, and how they host the next generation of AI.
My focus today is DevOps, Distributed Systems, Systems for AI, and AI Agents.
Previously Software Engineer at Riiid (2023–2025); before that, co-founded MyPlanIt and built TodoMall as CTO (2021–2023).
B.S. Computer Science at Yonsei University (2020–2027). Outside work, I build my own tools — including Bookmarket, a bookmark management application.
