Contern, Luxembourg
Summary
👤
Senior🎓
Top SchoolIvan Koveshnikov is a systems-focused software engineer with 10 years' experience building high-performance, resilient network software from embedded routers to in-kernel HTTP proxies and eBPF/XDP DDoS mitigation. At Gcore he architects and implements packet-filtering engines that parse L3–L7 protocols to protect legitimate traffic rather than indiscriminately blackholing flows, combining kernel-space C, eBPF/XDP and userland management components. Earlier work includes TempestaFW, an in-kernel L7 reverse proxy where he delivered zero-downtime runtime reloads and session persistence, and embedded router firmware with U-Boot and Yocto customizations. He favors C for systems work, is actively learning Rust, and prioritizes stability, performance, security and RFC-correct behavior at scale. A long-time open-source advocate, he pairs hands-on kernel and networking expertise with a pragmatic drive for transparent collaboration and operational excellence.
