Hi, I’m Wookje Han, an AI Developer Technology Engineer at NVIDIA. I work on performance optimization for LLM, video, and recommendation system workloads, with a focus on GPU kernel optimization using CUDA C++, PTX, cuteDSL, and CUTLASS.

Previously, I received my M.S. in Computer Science from Columbia University and my B.S. in Computer Science from Seoul National University (Summa Cum Laude).

Feel free to reach me at wookjeh@gmail.com!
