This is Xinpeng Wei and you may find me as WindowsXp on the Internet.
I'm a Member of Technical Staff at Amazon AGI SF Lab working on reinforcement learning systems to empower building next-generation AI agents.
Before that, I received my master's and bechalor's degrees from College of Computing, Georgia Institute of Technology and School of Software, Shanghai Jiao Tong University, respectively.
As a computer systems enthusiast, my current focus centers on building scalable and robust systems for large-scale machine learning like large language models(LLMs). Specifically, I have experience/am getting my hands dirty in distributed training(e.g. 5D parallel), RLHF framework(e.g. veRL), high-performance/parallel programming(e.g. CUDA, MPI), inference frameworks(e.g. vLLM, Sglang), and other fancy technologies in this emerging field.
I used to work on traditional systems topics like operating systems, cloud infrastructure(Kubernetes), and database systems.
I'm a slow walker, but I never walk backward.
