Contributed to the libsdl-org/highway repository by developing and refining vectorized operations for ARM SVE and SVE2 architectures, focusing on both feature delivery and code quality. Implemented new mask loading techniques and enhanced pairwise operations, while expanding backend support for saturated multiply-accumulate workflows. Addressed rotation logic correctness and improved test coverage, documentation, and code readability without altering core functionality. Used C++ and advanced SIMD programming, applying bit manipulation and compiler optimization skills to ensure cross-compiler reliability and maintainability. The work resulted in more robust ARM support, clearer code paths, and a strengthened test infrastructure for numerical and low-level computing tasks.
