Yuxuan Liu

I am a highly motivated software engineer with a strong background in software engineering and a passion for large language model infrastructure. With a Master's degree in Software Engineering from Shanghai Jiao Tong University, I have developed a solid foundation in computer science and software development. My research focus has been on large language model infrastructure, RDMA, NCCL, network systems, Linux kernel, virtualization, storage systems, and GPU Cuda.

Throughout my professional experience, I have worked as a C++ Development Engineer Intern at Shanghai Sixie Capital Management, where I optimized CPU, GPU, and NCCL performance for high-performance clusters. I have also worked as a Quant Developer Intern at Zhuhai Wizard Quant, where I developed an Order Book Engine for CME orders and implied orders. Currently, I am working as a Devops for LLM infrastructure at Hangzhou DeepSeek, where I isolate RDMA RoCE container networks for different roles using host and switch VLANs.

I am skilled in a range of programming languages, including C, C++, and Python, and have experience with Git, Vim, Tmux, Nvidia switch cumulus, Grafana, and Clickhouse SQL. I am a highly motivated and dedicated individual with a strong passion for software engineering and a drive to continuously learn and improve.
