Worked on the ACCESS-NRI/ACCESS-ESM1.6 repository, delivering configuration and deployment improvements over five months. Focused on Spack-based dependency and version management, this developer updated YAML configurations to pin component versions, align deployment environments, and reduce drift across model and UM components. Their work enabled reproducible builds, improved traceability, and ensured compatibility for new features and operational milestones such as Year 1 readiness. By leveraging skills in configuration management, package management, and version control, they addressed both feature delivery and bug resolution, maintaining clear commit histories and supporting cross-component coordination to streamline software deployment and validation workflows for the project.
February 2026: Implemented Year 1 compatibility by updating Spack dependencies in ACCESS-NRI/ACCESS-ESM1.6. Updated Spack configuration to reference the latest access-esm1p6 and um7 packages to ensure stable Year 1 operations. This work reduces deployment risk and aligns with Year 1 operational requirements; the change is captured in the corresponding commit for traceability.

June 2025, ACCESS-NRI/ACCESS-ESM1.6: Delivered a dependency alignment update by updating spack.yaml to reference newer development tags for access-esm1p6 and um7. This enables downstream access to recent fixes and improvements while maintaining build stability. Commit reference: bdbcff1abd4d92a8338d1d8004c32bb4258fe07f ("Update to new UM tag"). No major bugs fixed this month. Overall impact: reduced dependency drift, improved reproducibility, and accelerated access to fixes for downstream users. Technologies demonstrated: Spack configuration management, tag-based dependency pinning, Git-based change tracing, and build reproducibility practices.

In April 2025, delivered Spinup Environment Version Upgrades for the ACCESS-NRI/ACCESS-ESM1.6 project, upgrading multiple components in spack.yaml (access-esm1p6, cice4, um7, mom5, and access-generic-tracers) to reflect newer development branches/releases and enable a new spinup run. This work enhances reproducibility, reduces environment drift, and accelerates validation of the spinup workflow.
