Worked on the 2plist repository to enhance data completeness and integrity across multiple JSON datasets. Delivered a User Contributions Catalog Enhancement that added and updated contributor entries, including user links and completion percentages, within files such as master_duel.json, codependence.json, and gentlemens_clique.json. Coordinated updates across related files to ensure consistency and accurate attribution. Addressed a data integrity issue by correcting the trail identifier in the_old_trail.json, preventing mislinking and improving downstream reporting. Utilized skills in JSON manipulation, data management, and version control to strengthen data governance and traceability, focusing on reliable dataset maintenance and improved reporting readiness.
