During August 2025, Bharathi Selvam upgraded and streamlined PDF Viewer documentation across the syncfusion-content/document-processing-docs repository, focusing on .NET MAUI, Flutter, Xamarin, and UWP platforms. Bharathi applied cross-platform development and content management skills to expand coverage for annotations, form filling, and navigation, while also introducing new UWP documentation. In the syncfusion-content/flutter-docs repository, Bharathi removed obsolete Markdown files and restructured the table of contents to improve maintainability. Bharathi also deprecated outdated Xamarin and UWP documentation, ensuring consistency and reducing support overhead. The work demonstrated depth in technical writing, C# and Dart, and a strong emphasis on documentation accuracy and maintainability.
