During November 2025, Boris Zanin contributed to the KhronosGroup/Vulkan-ValidationLayers repository by addressing a critical Windows build failure. He identified and resolved an issue in the CMake configuration, where an incorrect parameter in the copy command was causing builds to fail on Windows platforms. By removing the problematic parameter, Boris improved the reliability of cross-platform builds and enhanced CI stability for downstream Vulkan validation workflows. His work demonstrated a strong command of CMake and build system configuration, resulting in a clean, maintainable solution. The fix was delivered with clear documentation, supporting future maintenance and reducing the risk of build regressions.
