Hi, I'm JinCheng Han 👋

Undergraduate at PKU, exploring the path from intelligent systems to ML infrastructure.

HJ Cheng's green 365-day AI coding calendar

Focus

ML Systems · LLM Inference · Computer Vision · Efficient Computing

Selected work

  • nanoPD — a from-scratch Prefill/Decode disaggregation inference engine for LLMs.
  • SLAM3R OnlineCam — real-time dense reconstruction from an online camera stream.
  • paperwise — deep reading for research papers with LLM reports, a vector KB, and a knowledge graph.

Dashboard sync

Collect and merge local Codex usage across macOS, Windows, and WSL. See the multi-device setup guide for first-time setup, SSH authentication, daily updates, and troubleshooting.

Understand the system. Build the system.
