During December 2024, Shufl Duf enhanced the hackclub/YSWS-Catalog repository by introducing a new feature focused on data management and user experience. They updated the programs.json data model to include a dedicated field for the Hack Store website URL, enabling the application to display and link directly to the store. This change laid the groundwork for improved external link handling and more complete, accurate program data. Working primarily with JSON and leveraging data management skills, Shufl Duf’s contribution addressed the need for better data quality and business value, though the scope was limited to a single feature without bug fixes.
