PROFILE
Dmitry Razdoburdin
Worked on the EmilHvitfeldt/xgboost and intel/ScalableVectorSearch repositories, focusing on enhancing cross-platform machine learning infrastructure. Delivered SYCL plugin improvements for xgboost, optimizing memory management and unifying objective calculations to boost performance and maintainability across CPU and GPU devices. Refactored core components using C++ and CUDA, introduced robust testing, and improved CI reliability by addressing include paths and test tolerances. For ScalableVectorSearch, expanded CI workflows to support ARM and macOS, enabling earlier detection of platform-specific issues. Leveraged CMake, GitHub Actions, and cross-platform development skills to strengthen code quality, resource efficiency, and deployment readiness across diverse hardware environments.
