Worked on CI/CD security hardening for the grafana/jsonnet-libs repository, focusing on improving the security of GitHub Actions workflows. The approach involved configuring YAML-based workflows to disable credential persistence between runs and defining explicit permissions, thereby reducing the risk of credential leakage and minimizing privilege exposure. Leveraging skills in CI/CD, GitHub Actions, and security best practices, the work enhanced the repository’s compliance readiness and auditability. No major bugs were reported or fixed during this period, and the changes were traceable through explicit commit references, ensuring transparency and alignment with industry standards for secure CI/CD pipeline management.
