Worked on the KhronosGroup/SPIRV-Tools repository to enhance geometry shader validation for cross-API compatibility. Focused on relaxing output location uniqueness checks when the GeometryStreams capability is present, enabling per-stream location sharing and aligning with D3D’s stream output model. Updated the SPIR-V validator logic in C++ to support per-stream aliasing, reducing artificial register pressure and improving translation between Vulkan and Direct3D. Developed comprehensive tests to verify correct behavior for output location uniqueness, ensuring robust shader validation. Demonstrated expertise in graphics programming, Vulkan API, and test-driven development, delivering improvements that facilitate better interoperability and resource management across graphics APIs.
