Worked on expanding the CI plugin ecosystem for the ecmwf/downstream-ci repository by integrating plume-plugin-wind-farm and plume-plugin-axe into the existing dependency management workflow. Focused on enhancing CI/CD automation, these additions enabled new wind-farm and axe integrations, streamlining continuous integration processes and reducing the need for manual configuration. Leveraged YAML for configuration and dependency management, ensuring that the new plugins were seamlessly incorporated into the CI pipeline. The work prioritized reliability and early issue detection, with no major bugs addressed during this period, and delivered a single feature aimed at improving the overall automation and extensibility of the CI system.
