Rockstar🎓
Top SchoolMaksim Panchenko is a seasoned software engineer in Mountain View with 11+ years focused on compiler and binary toolchain engineering, currently contributing at Facebook. He has deep, low-level expertise—designing compiler toolchains for consoles at Sony, leading binary-protection architecture at Virtuata/Cisco, and improving Sun’s dynamic analysis and binopt tools. Maksim is an active open-source contributor to LLVM and BOLT, where his work on binary optimization, jump-table fixes, dynamic relocations, and Linux kernel-specific features has improved stability and performance of widely used compiler tooling. Comfortable in both research and production environments, he pairs an MS in Applied Mathematics from MSU with a knack for untangling tricky, architecture-specific bugs that elude higher-level developers.

Role in this project:Back-end Developer
Back-end DeveloperContributions:499 reviews, 277 PRs, 234 pushes in 5 years 3 months
Contributions summary:Maksim's contributions primarily focused on enhancing the LLVM BOLT tool, a binary optimization and instrumentation tool. They addressed issues related to jump table handling, specifically correcting issues with trailing entries and preventing incorrect updates to function pointers. They also worked on improving the detection and handling of dynamic relocations. Furthermore, they refactored code, removed unused functions, and improved the overall structure of the codebase, and added support for Linux kernel specific features.
