Lucia Pena Perez focused on configuration management within the Clinical-Genomics/cg repository, addressing a critical bug related to software version metadata. She identified and corrected an incorrect YAML path in the tomte_pipeline_software_mqc_versions.yml file, ensuring accurate referencing of software version information throughout the pipeline. Using her expertise in YAML and configuration management, Lucia aligned file naming with project conventions to improve maintainability and consistency. Her targeted fix enhanced the reliability and stability of downstream pipelines by reducing the risk of version-mismatch errors. Over the month, her work prioritized quality assurance and risk reduction, contributing to more robust pipeline operations.
