Worked on security hardening of the CI/CD workflow for the evervault/evervault-js repository, focusing on reducing token exposure during automated versioning and tagging. The approach involved removing the default GITHUB_TOKEN from push operations and introducing an explicit token specifically for the changesets action, which improved authentication and minimized the risk of credential leakage. This adjustment addressed previous issues with push workflow credentials, resulting in more reliable and secure release processes. The work was implemented using YAML for workflow configuration and leveraged skills in CI/CD, DevOps, and GitHub Actions to enhance the overall security posture and stability of the repository’s automation.
