Enhance .NET MAUI RestaurantPOS

I have an in-house point-of-sale called RestaurantPOS, written in C# with .NET MAUI, targeting both Windows desktop and Android. Data is stored locally in SQLite and the core solution already builds and runs, but the user experience needs polishing.

The immediate goal is to refine the interface so it feels equally natural on a touchscreen tablet at the counter and on a keyboard-and-mouse workstation in the back office. That means responsive layouts, larger touch targets where appropriate, and shortcut-friendly controls for power users.

While doing so, I’d like you to keep the codebase clean (MVVM, dependency injection, async database calls) and make sure the SQLite layer remains fast and stable as records grow. If you spot any architectural issues during the UI work, recommendations or small refactors are welcome.

Deliverables
• Updated XAML and C# that switch gracefully between touch and traditional input
• Compiled .apk and .msix packages ready for test deployment
• A short change log and setup notes so I can reproduce your build

You’ll have access to the existing Git repository and sample data. If this fits your MAUI skill set, let’s discuss a sensible milestone plan and dive in.
