Worked on the tiiuae/ci-test-automation repository to address a critical issue in log analysis for CI/CD workflows. Delivered a targeted fix that updated Grafana log queries to use device IDs instead of MAC addresses, ensuring accurate log filtering and retrieval. This adjustment improved observability by preventing log loss caused by misidentification, thereby stabilizing automated test monitoring. The solution was implemented using RobotFramework and validated through focused testing and code review, maintaining dashboard integrity with minimal disruption. Demonstrated skills in CI/CD, log analysis, and test automation by resolving a complex bug, contributing to more reliable and maintainable test infrastructure.
