Worked on the columnflow/columnflow repository to address a critical bug in the CMS Minimal Analysis Template, focusing on stabilizing the analysis workflow for high-energy physics datasets. Used Python to resolve dataset naming discrepancies and update jet and muon selection variables, ensuring alignment with a validated JSONPOG mirror tag. This approach reduced configuration drift and improved reproducibility across different datasets and configurations. Demonstrated skills in bug fixing, configuration management, and data analysis by validating dataset conventions and external references, resulting in a more reliable analysis pipeline and increased confidence for analysts working with the CMS minimal analysis template in collaborative environments.
