Summary
🤩
Rockstar🎓
Top SchoolSerge Kosyrev is an experienced technologist and business development leader with 18 years building secure systems, low-level tooling and reproducible infrastructure from kernel and hypervisor work to deployment automation. He led a 13-person research-and-development team at Positive Technologies, driving architecture, build systems, CI and production-grade prototypes for hypervisor-based secure endpoints while also directing Intel ME research and tooling. A Haskell and bare-metal hacker by practice, Serge has substantial open-source DevOps contributions to high-profile Cardano projects and NixOps, improving build pipelines, CI, deployment automation and fault-injection for blockchain nodes and wallets. Now in business development at Symbolian, he pairs deep systems engineering chops with product and go-to-market experience, able to translate complex technical tradeoffs into practical roadmaps. Outside work he pursues endurance habits—mountain running and fasting—which echo his methodical, long-horizon approach to engineering and research.
