Worked on the zitadel/zitadel-charts repository to enhance Helm chart deployment by implementing explicit namespace scoping for all namespaced resources. This approach involved updating Helm templates and introducing automated tests to ensure that every resource type correctly specifies its namespace, thereby strengthening multi-tenant isolation and reducing the risk of deployment misconfigurations. The work leveraged Kubernetes, Helm, and YAML, with Go used for test automation and validation. These improvements focused on production reliability and governance, ensuring that deployments are more predictable and secure without introducing new bugs. The changes were integrated with CI-ready checks to support robust DevOps workflows.
