During April 2025, Arng worked on the cisagov/XFD repository, focusing on improving the build process by updating the ATC Framework version referenced in the project’s Dockerfile. By pinning the framework to the latest commit, Arng ensured that builds consistently used the most recent dependencies, reducing drift and enhancing reproducibility. This disciplined approach to build automation and dependency management contributed to a more reliable CI/CD pipeline and smoother upgrade paths for downstream systems. The work demonstrated proficiency in Dockerfile maintenance and DevOps practices, though the scope was limited to a single feature update without additional bug fixes or broader architectural changes.
