Worked on the EruditorGroup/profi-design-system repository to modernize infrastructure by upgrading all GitHub Actions CI/CD workflows to version 4. Focused on replacing deprecated v2 and v2.1.7 actions with current versions across multiple YAML workflow files, including common.yaml, lint.yaml, npm.yaml, storyshots.yaml, and test.yaml. Consolidated these updates into a single commit to streamline the transition and ensure compatibility with future GitHub Actions releases. Leveraged skills in CI/CD and GitHub Actions, with extensive use of YAML for workflow configuration. This work improved build reliability, enhanced caching efficiency, and strengthened the security and maintainability of the project’s automation pipelines.
