Brief
I am currently an LLM serving infra engineer at Alibaba Group and a joint post-doc of Alibaba & ZJU. I earned my CS Ph.D & B.E. degrees under the supervision of Prof. Yuchong Hu & Prof. Dan Feng at HUST
.
My previous Ph.D research mainly focused on building high-performance and fault-tolerant new memory systems.
This blog contains some random paper reading notes and trivial thoughts.

- Enjoying the process of building something:
monkeytyping on - Randomly contributing codes to small open-source projects
- A homelab server with super limited budgets. Some experiments from the build were posted on Hacker News
- A LLM webui with broad support for top-tier LLMs.
