Hello, I am Jongseo Lee, an undergraduate student majoring in Computer Science at KAIST.
My primary research interests lie in Theoretical Computer Science, particularly combinatorial optimization and approximation algorithms. I am also deeply interested in solving complex technical challenges in industry-scale systems.
I have over four years of professional experience as a Software Engineer. Most recently, I worked at Moloco, Inc. (2023 – 2025), where I developed large-scale real-time bidding systems and experimentation frameworks. Prior to that, I worked at Chai Corporation, Sendbird, and completed an internship at NAVER.
I am always open to new research collaborations and exciting engineering opportunities — please feel free to reach out.
