Summary
🤩
Rockstar🎓
Top SchoolVadim Zyarko is a senior software engineer based in Concord, CA, who brings deep systems and backend expertise rooted in a Master's in Applied Mathematics from MIPT and over two decades of industry experience. Currently at Sysdig, he focuses on performance-sensitive cloud-native runtime security, contributing notable backend improvements to the widely used Falco project—optimizing rule loading, event processing, and IPv6 handling in core libs. His career spans high-impact engineering roles at YapStone, Genesys, and Alcatel‑Lucent, where he moved between hands-on optimization and platform-level design. Colleagues rely on him to refactor legacy code, remove technical debt, and design efficient data structures that measurably boost throughput. He combines rigorous analytical training with pragmatic engineering, often finding non-obvious performance wins in under-optimized subsystems.
