Worked on security hardening for the portworx/helm repository by updating Docker image versions for MongoDB, Prometheus, and Alertmanager within Helm chart configurations. Focused on addressing high and critical CVEs, the work improved the security posture and reliability of containerized deployments. Leveraged skills in containerization, DevOps, and Helm Charts, using yaml to ensure precise configuration changes. Maintained operational artifacts and updated changelogs to document the security updates, providing clear guidance for operators. Ensured end-to-end traceability by referencing exact commits, supporting auditability and rollback readiness. The work targeted reducing vulnerability exposure and enhancing deployment practices for cloud-native environments.
