Hello, I am Jongseo Lee, an undergraduate student majoring in Computer Science at KAIST.
My primary research interests lie in Theoretical Computer Science and Combinatorics, including (but not limited to) graph parameters, 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.
I am always open to new research collaboration opportunities — please feel free to reach out.
