Summary
🤩
Rockstar🎓
Top SchoolStanislau Hlebik is a seasoned software engineer with 12 years of experience building backend systems and improving core infrastructure at scale, with tenures at Facebook, OpenAI, and currently Isomorphic Labs in the UK. He has a strong track record in performance-sensitive C++ and systems work, contributing to high-profile open-source projects such as HHVM, Buck, RocksDB and Folly—often focusing on portability, build systems, and low-level file I/O. At Facebook he drove refactors and feature additions that improved Java compilation flows, cross-platform compatibility, and database iterator semantics, showing a habit of tackling thorny, production-critical issues. Equally comfortable navigating build tooling and storage internals, he brings pragmatic engineering that reduces technical debt while enabling new functionality. An alumnus of Belarusian State University and Yandex School of Data Analysis, he pairs academic grounding with hands-on experience across large-scale codebases.
