Worked on the parthenon-hpc-lab/parthenon repository, focusing on improving the interpolation subsystem within a high-performance computing context. Addressed a correctness issue in type checking by replacing typeid with std::is_same_v and introducing explicit validation for Coordinates_t against UniformCartesian, enhancing type safety and maintainability. Utilized C++ and template metaprogramming to modernize the codebase, aligning it with current best practices and improving overall robustness. Updated documentation in Markdown to ensure traceability of changes. The work contributed to greater reliability in simulation workflows and increased developer confidence, reflecting a careful, detail-oriented approach to code quality and long-term maintainability.
