PROFILE
Igor Klemenski
Worked on the microsoft/retina repository to enhance end-to-end eBPF validation and network metrics collection for Mariner Linux, focusing on production-grade reliability and performance. Introduced a distro-aware testing setup and refactored drop reason metrics to use fexit-based collection, reducing system calls and improving accuracy. Developed a FIPS-enabled test infrastructure spanning Mariner, AzureLinux, and Ubuntu, consolidating compliance across environments. Stabilized CI workflows by addressing YAML validation and merge logic, and improved kernel compatibility by conditionally loading eBPF programs based on system version. Leveraged Go, YAML, and system programming expertise to deliver robust, compliant, and efficient cloud infrastructure testing solutions.
