During August 2025, Summpot developed the Auto Route option for Tun mode in the 2dust/v2rayN repository, enhancing user configurability by automating routing setup. The work involved implementing changes across configuration models, MVVM bindings, and the user interface, ensuring seamless integration and consistent behavior throughout the application. Using C#, XAML, and MVVM architecture, Summpot focused on reducing manual routing steps and minimizing user error, while maintaining clean, testable code. Although the contribution was limited to a single feature within the month, the depth of cross-layer integration demonstrated a solid understanding of both UI development and application architecture principles.
