Rockstar🎓
Top SchoolLiu Wei is a Senior Software Engineer in Shanghai with 14 years of experience building high-performance, networked systems and databases in Rust, C/C++ and Lua. He has deep expertise in Linux kernel and application programming, TCP/IP stacks, CDN/live streaming protocols (RTMP/HLS/FLV), and observability, and currently leads the ClickHouse-backed storage layer for Tencent Cloud’s logs and traces compatible with Loki and OpenTelemetry. His open-source contributions include stabilizing Nebula Graph and advancing core Nginx/Tengine modules—work that spans concurrency fixes, backup/restore reliability, and dynamic module support for large-scale production systems. At Alibaba and Taobao he architected CDN live streaming and SPDY support in Tengine, reducing CPU usage and enabling dynamic module loading early in the project’s lifecycle. Colleagues rely on him to bridge system architecture and low-level implementation, often surfacing subtle race conditions and preventing production crashes. He pairs pragmatic production focus with a history of impactful OSS fixes that improve reliability at internet scale.
