Bio / CV
Software Engineer (Backend)
I build backend and network systems for latency-critical real-time streaming.
I am a backend and network systems engineer working on latency-critical real-time streaming. My recent work spans transport protocol design, congestion control, packet loss mitigation, Linux networking, and production-scale observability.
At Tencent START Cloud Gaming, I built and operated networked systems across edge and WAN environments and helped move research ideas into production. I received my M.S. in Computer Networks from Tsinghua University and B.Eng. in Computer Science from Nankai University.
Experience
Network Systems Engineer
Tencent START Cloud Gaming
Built a high-performance multi-protocol transport stack for real-time streaming, supporting low-latency, high-bitrate, and low-stutter video delivery.
Productionized telemetry-driven packet loss mitigation for cloud gaming, reducing stutter by more than 30% and leading to an NSDI '26 paper.
Shipped congestion control and edge traffic-control systems, including lock-free and zero-copy components, while coordinating with operations and compute teams around QoS, SLO, and cost.
Network Engineer Intern
Alibaba Cloud / DAMO Academy
Built a transparent proxy over MP-QUIC for robust mobile connectivity and evaluated flow scheduling and queueing policies for multi-path transport.
