PROFILE

Bart Geesink

Worked on enhancing containerized deployments and configuration reliability across OpenConext-engineblock and grafana/loki repositories. Delivered Docker logging improvements for OpenConext-engineblock by implementing JSON logging with multiline support and directing authentication logs to stderr, while upgrading the logging format to JSON5 and removing legacy PHP 5.6 tests to streamline release management. In grafana/loki, addressed a critical configuration bug by updating Helm charts to ensure CiliumNetworkPolicies port definitions use string values, aligning with YAML specifications and reducing deployment errors in Kubernetes environments. Utilized skills in Docker, Helm, and YAML to improve observability, release stability, and configuration accuracy throughout the development cycle.
