Worked on the LLNL/RAJA repository to enhance the IndexLayout API and its test infrastructure over a two-month period. Developed new API methods to expose size and stride information, improving indexing performance and consistency across host and device execution. Refactored core functions with RAJA_INLINE and RAJA_HOST_DEVICE annotations to optimize cross-device inlining and reduce divergence in indexing logic. Expanded unit test coverage for IndexLayout, validating size and dimension properties in both 1D and 2D layouts. Leveraged C++ development, metaprogramming, and unit testing skills to deliver robust, performance-oriented features that streamline kernel development and increase release confidence without introducing regressions.
