During March 2025, Manuel focused on improving log observability in the tiiuae/ci-test-automation repository by addressing a critical issue in Grafana log queries. He replaced the use of MAC addresses with device IDs for log filtering, ensuring accurate retrieval and preventing log loss caused by misidentification. This targeted fix stabilized CI/CD and test automation workflows by enhancing the reliability of log analysis. Manuel validated the solution through targeted testing and code review, maintaining dashboard integrity with minimal disruption. His work leveraged skills in CI/CD, log analysis, and test automation, utilizing RobotFramework to deliver a robust and maintainable improvement.
