Rockstar🎓
Top SchoolMaciej Grzywacz is a software research engineer with 5+ years of experience building compiler toolchains and low-level infrastructure, currently designing compiler support for new hardware at Intel in Gdańsk. He specializes in C++ and LLVM backend work, having implemented custom RISC-V backend extensions, optimization passes, and runtime libraries that bridge simulator quirks to usable toolchains. His contributions to the Intel Graphics Compiler show deep expertise in atomic operations, codegen passes, and shader compilation flows across GLSL, LLVM IR and assembly. Beyond coding, he co-designed hardware features and shaped testing and CMake infrastructure to speed builds and track compiler performance, blending systems-level thinking with practical developer ergonomics. Colleagues rely on him to translate hardware specs into compiler-friendly ISAs and reproducible build and test workflows.
