Summary
🤩
RockstarVyacheslav Egorov is a Principal Software Engineer based in Riga, Latvia, with over five years of professional experience and a decade-long background in game and systems development. At Roblox since 2020 he focuses on low-level performance and code generation, contributing to JIT/compiler internals and build stability for large codebases. Previously a senior engineer at Game Insight, he shipped production game systems and scaled engineering practices across teams. His open-source work on the Luau language shows hands-on expertise in x64 instruction emission, native state management, and re-optimizing math functions for measurable performance gains. Colleagues rely on him for pragmatic, low-level problem solving that bridges compiler theory and real-world product constraints. He combines deep systems knowledge with a steady track record of fixing tricky build and optimization issues in high-throughput environments.
