During March 2025, Oh worked on the lauraleibman/NJCem repository, focusing on enhancing content enrichment and data presentation through configuration management. They added biographical image assets to the objects directory, improving the depth and quality of character profiles. Oh updated the _config.yml file to switch metadata display to HTML output, optimizing user-facing presentation. They also enabled CSV metadata processing by modifying the Google Sheets URL, supporting more flexible data workflows. All changes were implemented using YAML and configuration management skills, resulting in a refreshed, up-to-date configuration that improved both data processing capabilities and the overall user experience for the project.
