Senior🎓
Top SchoolChen Haiyang is a Senior Software Engineer with 10 years of experience specializing in Linux kernel and network systems development, combining 14 years of C programming expertise with deep knowledge of x86/ARM assembly and architecture. He has designed and implemented cloud DDoS defense, DNS, TOA kernel modules, and DPDK-based anti-DDoS components at KnownSec, and previously worked on ADC features and distributed SSI systems on FreeBSD. Skilled in concurrency, kernel memory subsystems (SLUB, RCU, spinlocks), ELF/dynamic loading, and protocols from MAC/VLAN to TCP/IP, he excels at diagnosing subtle concurrency bugs and memory corruption by reading and instrumenting source. CISSP-certified and fluent in Python, he bridges low-level systems engineering with security-minded design, and often investigates mechanisms by tracing code paths rather than relying on documentation alone. Based in Beijing, he brings a pragmatic, code-first approach to building robust, high-performance networking software.
