Worked on kubeshop/testkube to implement secure PostgreSQL DSN management by leveraging Kubernetes Secrets and enhancing Helm templates for conditional secret referencing. This approach reduced the risk of credential exposure and enabled more dynamic configuration during deployments, aligning with cloud-native security standards. The work involved updating Helm values and templates, moving PostgreSQL configuration scope to the testkube-api, and adding clarifying comments in values.yaml to define configuration boundaries. Minor code hygiene improvements, such as newline handling, were also included to maintain code quality. The project utilized Go and YAML, demonstrating backend development skills with a focus on Kubernetes and Helm integration.
