PROFILE
Jean M. Sexton
Worked on the AMReX-FHD/FHDeX repository to enhance both code quality and development workflows over a two-month period. Focused on refactoring C++ and Fortran components, improving code readability, and correcting statistical calculations in particle generation routines. Led a comprehensive overhaul of the CI/CD pipeline using GitHub Actions, updating CUDA and Ubuntu baselines, expanding test coverage, and integrating build caching with ccache. Addressed build reliability by refining error reporting, artifact management, and dependency scripts. Emphasized maintainability through code formatting, removal of unused parameters, and consistent naming, resulting in more robust scientific computing workflows and streamlined repository maintenance.
