About
Jincheng Han
Student / Developer
I am an undergraduate student majoring in Intelligence Science and Technology at Peking University. I started out in Computer Vision — 3D reconstruction, rendering, and recognition — before shifting my focus fully to ML Systems. These days I care more about what happens under the hood: CUDA kernels, inference optimization, distributed training, and P/D disaggregation.
