Rockstar🎓
Top SchoolPiotr Sobczak is a GPU compiler engineer with seven years of focused experience and a decade-plus background in embedded and graphics software, currently driving AMDGPU backend improvements at AMD. He has a strong compiler toolchain pedigree from Arm and practical systems work spanning OpenGL ES, video streaming, BSPs and Android from consulting roles at Mobica. At AMD he contributed performance-focused code generation and IR optimizations to the high-profile LLVM project, including vector simplifications, FMA fixes and barrier optimizations with accompanying tests. Educated at Politechnika Łódzka with an Erasmus stint at the University of Southern Denmark, he blends academic grounding with pragmatic engineering and a proven track record of shipping low-level, performance-critical features.
