Andre Harendt modernized and maintained the iits-consulting/charts repository over two months, focusing on Helm chart reliability and deployment workflows. He migrated the ArgoCD Helm chart from Bitnami to the official ArgoProject version, updating dependencies and enabling bootstrapping without storageClasses. Andre enhanced Git credentials handling and Docker pull secret support within Helm charts, and ensured documentation accurately reflected these changes. He addressed password generation reliability by implementing a temporary image source workaround and fixed ArgoCD ingress routing for stable deployments. Working primarily with Go, YAML, Helm, and Kubernetes, Andre delivered maintainable solutions that improved chart stability and operational clarity.
