Contributed to ORNL/GridKit by delivering targeted enhancements to its numerical solver infrastructure over a two-month period. Focused on upgrading the SUNDIALS library, the work improved the IDA and KINSOL solvers through memory management optimizations, initialization fixes, and code cleanup, resulting in greater stability and efficiency for large-scale simulations. Subsequent efforts modernized dependency management by aligning the repository and CI pipelines with SUNDIALS 7.4.0, updating CMake build files and Spack package requirements to ensure compatibility. Leveraged C++, CMake, and CI/CD practices to strengthen reproducibility, maintainability, and future extensibility of GridKit’s scientific computing workflows.
