Developed foundational API documentation for the SAM.gov Contract Awards API draft within the GSA/open-gsa-redesign repository, focusing on improving developer onboarding and integration. The work involved assembling a comprehensive Markdown reference that details the API’s overview, features, data types, access requirements, and includes practical request and response examples along with error codes and help resources. By standardizing documentation artifacts and references, the developer established a clear structure for future quality assurance and governance. The technical writing and API documentation skills applied ensured that the draft documentation is self-contained, version-controlled, and positioned to support both immediate and future development needs.
