Summary
👤
Senior🎓
Top SchoolGuillaume Marques is a GPU compiler engineer based in California with a decade of hands-on experience building C++ compilers and LLVM-based optimizations for SIMD/SPMD and GPU targets. Currently at Apple, he has previously implemented a CPU SPMD vectorizer and advanced optimizations (including BOSCC) at Codeplay, and brings deep practical knowledge of LLVM IR, performance benchmarking, and compiler testing. A former teaching assistant who led the Tiger Compiler project at EPITA, he blends strong engineering with mentorship and a solid grounding in compiler theory and modern C++ best practices. An avid reader of classic C++ and compiler texts, he pairs theory with production impact—often surfacing non-obvious performance wins through careful vectorization and IR-level transformations.
