In June 2025, delivered reliability and simplicity improvements across ginkgo and Artemis, focusing on build hygiene, resource-aware testing, and test robustness. For ginkgo, removed a placeholder pre-commit hook and unused CMake config, simplifying the build process and developer tooling. Also, added a guard to abort MPI tests when insufficient processes are available, preventing misconfigured runs in constrained environments. For Artemis, fixed inconsistencies in C++ exercise tests and improved XML generation by stripping non-ASCII characters and ensuring an empty test suite is created when needed, enhancing test determinism and parser resilience. Overall impact: reduced build and test failures, faster feedback loops for developers, and stronger cross-repo code quality. Technologies demonstrated: CMake, pre-commit tooling, MPI, C++, XML parsing, and test infrastructure hygiene.
