Worked on the AvaloniaUI/avalonia-docs repository to deliver a consolidated set of Simplified Chinese documentation translations, focusing on platform hosting, services, UI concepts, XAML, and installation guides. Used C#, Markdown, and XML to ensure that localized content remained synchronized with the latest upstream changes, reducing documentation drift and improving accessibility for Chinese-speaking developers. The approach involved upstream synchronization of core documentation and installation materials, as well as ongoing alignment of localization guides. This work enhanced the accuracy and usability of Avalonia documentation, supporting cross-platform development and making technical resources more accessible to a broader developer audience.
