Summary
🤩
RockstarJeff Lucovsky is a Principal Engineer with decades of low-level systems and networking experience, currently leading Suricata development and traffic-analysis engineering at Corelight. He specializes in high-speed network security (100+ Gbps), NUMA-aware multi-core architectures, and zero-copy packet inspection across physical and virtual form factors. A core Suricata contributor, Jeff has improved stability, memory safety, and HTTP/SSL content inspection in a widely used open-source IDS/IPS engine. His background spans OS internals, distributed storage, and appliance drivers, with practical experience porting DPDK and tuning data-paths for carrier-class performance. Known for turning research prototypes into production-grade, testable systems, he pairs hands-on debugging (C/C++, Python, ASAN, gdb) with cross-team technical leadership. Based in North Carolina, he brings uncommon depth in both historical UNIX internals and modern high-throughput network security.
