Rockstar🎓
Top SchoolPavel Chupin is a senior compiler and libraries engineering leader with 14 years of experience building and managing toolchain and runtime teams across Intel and SiFive. He has led production compiler products and open-source projects (including stewardship of intel/llvm and deep contributions to AOSP bionic and platform development) with a focus on LLVM/GNU toolchains, performance libraries, and cross‑architecture compatibility. Pavel blends hands-on system-level engineering—fixing x86_64 syscall/relocation issues, alignment bugs, and build-system targets—with people and product management for global teams. Based in San Jose, he brings a rare combination of compiler QA, low-level systems expertise, and strategic leadership informed by a MIPT background in compiler testing and static analysis.
