PROFILE

Kaitlin Peng

Kaitlin Peng contributed to multiple compiler and graphics infrastructure projects, focusing on test coverage, code optimization, and documentation. In the llvm/offload-test-suite repository, Kaitlin expanded HLSL and floating-point test suites, implemented Float16 ULP-based comparisons, and enhanced ldexp and select function validation across diverse data types. She optimized the DirectX backend in intel/llvm by scalarizing integer vector operations and refining dead code elimination. Kaitlin also improved HLSL resource lowering in the arm/arm-toolchain and clarified language specifications in microsoft/hlsl-specs. Her work, primarily in C++, HLSL, and LLVM IR, demonstrated depth in low-level programming, testing, and maintainable code architecture.
