Senior🎓
Top SchoolChangchun Zhang is a Principal Software Engineer based in Greater Boston with 13 years of deep experience in high-performance real-time communications, networking dataplanes, and multi-core packet processing. He designs and optimizes platform and architecture-level solutions—leveraging DPDK, Cavium OCTEON, SIMD/AVX512, QAT and Linux kernel/device-driver techniques—to squeeze latency and throughput from heterogeneous parallel engines. At Oracle he has led feature and performance work on media streaming security (SRTP/TLS/IPSec), transport integration, and massive-core packet datapaths, bringing production-grade scalability to complex telecom products. His background spans embedded and wireless systems research (Ph.D. work on cognitive radio and SDR testbeds) through carrier-grade signaling and LTE/EPS platform development, giving him rare end-to-end visibility from silicon to cloud. Colleagues rely on him for pragmatic architectural tradeoffs and for turning advanced crypto/offload primitives into measurable capacity gains.
