Idan Mantin developed a Kubernetes Secrets-based gateway cache encryption key management feature for the akeylesslabs/helm-charts repository, enabling secure auto-scaling in environments without network connectivity. He updated Helm chart values, refined templating logic, and added RBAC permissions to ensure the encryption key is securely stored and referenced when cluster caching is enabled and no secret exists. Using Go and YAML, Idan’s work aligned deployment practices with best-practice secret management, reducing the risk of key exposure. The feature improved operational security and reliability by supporting autonomous cluster scaling while minimizing external dependencies, demonstrating depth in DevOps and Kubernetes engineering.
