👤
SeniorJiho Jung is a Senior Solutions Engineer based in Seoul with over 15 years of hands-on experience designing and shipping commercial network security products including firewalls, VPN, IPS and UTM. He combines deep kernel- and userspace-level expertise—Linux kernel network stack, multi-threaded kernel programming, event-driven socket work with libevent—and practical embedded systems skills like building root filesystems from scratch. Jiho has led development of high-performance security engines (packet filtering, NAT, session tables, IPS, IPsec) and commercialized Suricata for product use, later pivoting to SDN and cloud VPC firewall features for large-scale deployments. Known for heavy debugging chops and algorithmic work (custom packet classification and hash table adaptations for billion-tuple scale), he bridges low-level optimization with production-grade cloud networking. He brings repeatable delivery across startups and global cloud projects, with a pragmatic focus on performance, reliability and real-time state synchronization.
