Senior🎓
Top SchoolSabyrzhan Tasbolatov is a Senior Software Engineer with 11+ years of experience building high-performance backend systems across ride-hailing, FinTech, security tooling and embedded devices. He combines deep security expertise (OSCP, OSCE) and offensive-research experience—co-founding a red-team startup and contributing kernel fuzzing fixes to Google's syzkaller project—with production engineering at scale, including low-latency trading systems and distributed pricing backends. His work spans Linux kernel exploits and hardening, high-throughput trading pipelines optimized with GPU backtesting, and resilient cloud-native operations (k8s, CI/CD, Helm). Pragmatic and performance-focused, he has improved legacy systems by orders of magnitude and introduced robust testing and race-condition fixes in widely used open-source tooling. Based in Astana, he also teaches reverse engineering at the graduate level, blending academic rigor with hands-on delivery for mission-critical systems.
