PROFILE
Stefan Sokolovic
Stefan Sokolovic contributed to core GPU and machine learning infrastructure across microsoft/onnxruntime, ROCm/rocm-libraries, and pytorch/pytorch. He enabled ROCm execution provider support for INT8 quantization benchmarks, expanding hardware visibility and optimizing AMD GPU deployments using Python and benchmarking expertise. In ROCm/rocm-libraries, Stefan implemented experimental Stream K support for RDNA architectures by adapting assembly instructions and compiler logic, broadening performance analysis capabilities. He also addressed a critical Windows ROCm build crash in PyTorch by correcting C++ header includes, ensuring stable DLL exports. Stefan’s work demonstrated depth in low-level programming, performance optimization, and cross-platform GPU software engineering.
