Xiaofeng Wang is a Linux software engineer with 11 years of hands-on experience building high-performance C++ backend systems, based in Haidian District, Beijing. At BQVISION he applies deep systems and networking expertise across production services, and his open-source work shows practical contributions to industrial-grade projects like Apache brpc and ZLMediaKit. He has improved RPC and HTTP/REST handling, added Protobuf compatibility, enhanced media streaming (HLS, webhook) and strengthened UDP/SSL networking in lightweight C++ frameworks—skills that suit low-latency, high-concurrency environments. With a mathematics degree from CCNU, he brings rigorous problem-solving to debugging, refactoring and cross-project integrations, and is comfortable touching build systems, IDE tooling and protocol-level details. Notably, his contributions often focus on subtle but impactful fixes (e.g., multi-address discovery, socket options, and non-ASCII formatting) that improve robustness in large codebases.
