Worked on enhancing the Express Document SDK documentation within the AdobeDocs/express-add-ons-docs repository, focusing on consolidating API references and expanding coverage for new interfaces and type aliases related to text styling and list management. Leveraged Markdown and technical writing skills to document BitmapImage changes, including the addition of bitmapImage.md and updated API references, while also providing detailed changelog notes for document sandbox features. Improved documentation quality by resolving link validation issues and introducing new linting practices, which increased reliability and consistency. These efforts streamlined developer onboarding, improved API discoverability, and reduced integration risk for teams integrating with the SDK.
