Rockstar🎓
Top SchoolJianzhang Peng is a seasoned network performance engineer with 10 years of experience designing high-throughput infrastructure and load-balancing systems across Baidu, Huawei, Banggoo Networks, and Time Research. He led core development of layer-4/7 load balancers, DNS/GSLB, and cloud load balancer products, combining hands-on protocol-level optimization with architecture-level leadership. Jianzhang is the author of dperf, a widely used 100Gbps network load tester on GitHub, and has contributed deep TCP/UDP, VXLAN, KNI/VLAN, and RTT measurement improvements that reveal a focus on realistic, precise performance validation. Based in Singapore and holding a PhD in Computer Science from USTC, he blends rigorous academic training with pragmatic product delivery in high-performance networking. An understated strength is his knack for squeezing predictable behavior out of complex packet pipelines—turning theoretical throughput into repeatable benchmarks.
