During their work on the NGWPC/ngen repository, Klarkin refactored the Docker-based build system to improve MPI build stability and streamline mpi4py installation. By updating Python versions and optimizing library build and install steps within the Dockerfile, they enhanced reproducibility and reduced image size, directly benefiting CI/CD reliability. Klarkin addressed installation syntax issues for mpi4py, resolving persistent MPI package failures and stabilizing integration with downstream systems. Their approach emphasized dependency management and artifact cleanup, resulting in faster CI cycles and easier maintenance. The work demonstrated depth in Docker, Shell scripting, and package management, delivering a more robust and maintainable build pipeline.
