Worked on enhancing the Covidcast API documentation within the cmu-delphi/delphi-epidata repository, focusing on improving developer experience and documentation quality. Consolidated and restructured the API docs by introducing a dedicated page for constructing API queries, which improved navigation and accessibility. Addressed documentation issues by correcting dead links, typos, and header inconsistencies, and ensured accurate cross-referencing and changelog updates. Clarified terminology by aligning with current HHS standards and added detailed guidance on epiweeks, dates, and lists to reduce user errors. Utilized Markdown and technical writing skills to synchronize metadata and update UI-related headers, reflecting current product terminology throughout.
