Worked on the shader-slang/slang repository to address a critical issue in WGSL 64-bit unsigned integer emission. Delivered a targeted fix in C++ that ensures 64-bit types emit as 'u64', aligning with the WGSL specification and resolving shader validation errors during compilation. The solution involved updating slang-emit-wgsl.cpp to directly emit 'u64' for UInt64Type and adding comprehensive tests to verify correct WGSL output for both u64 and i64 types. Demonstrated expertise in C++ programming, GPU programming, and shader development, while collaborating across teams to improve reliability and integration for 64-bit buffer access in GPU workflows.
