Worked on the datacommonsorg/docsite repository to deliver a focused revamp of the Data Source Catalog, emphasizing content management and documentation quality. Updated the catalog by removing outdated entries, adding new datasets, and reorganizing the Biomedical section to enhance accuracy and discoverability for users. Utilized Markdown to streamline documentation, reduce redundancy, and clarify data source listings, making it easier for data engineers and researchers to onboard and locate relevant information. All changes were version-controlled and committed to the repository, resulting in improved data source reliability, reduced maintenance overhead, and better alignment with current datasets for informed decision-making and efficient workflows.
