Worked on enhancing and maintaining documentation for the Syncfusion PDF Viewer across multiple platforms, focusing on the syncfusion-content/document-processing-docs repository. The work involved upgrading and expanding documentation for .NET MAUI, Flutter, Xamarin, and UWP, with particular attention to annotations, form filling, navigation, and customization features. Applied skills in C#, Dart, and Markdown to restructure content, remove deprecated or obsolete files, and ensure cross-repository consistency. Addressed compilation and table of contents integrity issues to prevent broken links and improve maintainability. This approach reduced user confusion, aligned documentation with the product roadmap, and streamlined support by delivering clear, accurate technical guidance.
