Mathias Petermann developed configurable authentication and deployment features across two open source projects. For netbox-community/netbox-chart, he enabled dynamic SSO role mapping by allowing staff and superuser roles to be set via Django settings, replacing hardcoded values and aligning NetBox deployments with enterprise identity providers such as Keycloak and GitLab. In aquasecurity/trivy-operator, he introduced a Helm chart option to reference externally managed Kubernetes secrets for Trivy configuration, updating values.yaml and documentation to support secure, flexible deployments. His work leveraged Python, YAML, and Helm, demonstrating depth in backend development, authentication, and configuration management while improving maintainability and security.

December 2024: Delivered configurable SSO role names via Django settings for netbox-chart, enabling dynamic mapping of staff and superuser roles from Keycloak and GitLab configurations. Removed hardcoded values, updated docs, and enhanced the auth sso_pipeline_roles script to read role mappings from Django settings (commit 8b51fa296cdeb4585eefa92895c1b38099be39c3). This work improves deployment flexibility, reduces misconfiguration risk, and strengthens identity-provider alignment across environments.
