Worked on the shader-slang/slang-rhi repository to enhance the reliability of shader variable layout reflection in C++ graphics pipelines. Focused on stabilizing compiler and layout behavior for modules with global ConstantBuffers, the work addressed a critical assertion failure by ensuring composite component types are properly linked after creation. Defensive null checks were introduced across Vulkan, WGPU, and D3D12 backends, improving robustness during layout processing. Additional test coverage validated end-to-end module import paths, while refactoring of ShaderProgram initialization and updates to the loadProgram API contract streamlined initialization logic. Utilized C++, CMake, and shader development expertise throughout the process.
