I have an existing Xamarin Forms application that already runs smoothly on iOS and Android. I now need the full codebase moved over to .NET MAUI so I can keep pace with the latest tooling and long-term platform support. While you perform the migration, I also want to introduce a handful of new features to take advantage of MAUI’s capabilities rather than simply doing a like-for-like port. Core scope The current app has about the usual mix of pages, view-models, and XAML-based UI. All functionality that works today must compile, deploy, and behave the same on iOS and Android after the upgrade, plus the agreed-upon enhancements. Any platform-specific tweaks (e.g., iOS status bar, Android permission prompts) should be handled with MAUI best practices. Key deliverables • Up...

Admin sees the same warnings in a consolidated panel. I’m happy with mainstream cross-platform stacks such as Flutter, React Native, or Xamarin so long as performance is smooth and the Windows build installs without side-loading. A lightweight web API with a secure SQL or NoSQL backend is fine; just make sure it scales. Deliverables 1. Source code with clear build instructions for all three platforms. 2. Simple cloud or on-premise deployment guide for the backend. 3. Tested notification workfl...

I have a collection of Java / Kotlin classes that sit at the heart of my Android app. They manage in-memory data structures, expose that data to the rest of the app, and synchronise it with our back-end through a handful of REST-style APIs. I now need the exact same behaviour expressed in clean, idiomatic C# so the project can be compiled under the .NET Android toolchain (Xamarin or MAUI—whichever you prefer). Your task is to translate every class, interface, and public method signature to their .NET equivalents, preserving naming, access levels, and logic while embracing C# conventions such as properties, async/await, and nullability annotations. The resulting code must build and run in Visual Studio, target current Android SDK levels, and integrate with the existing API end...

Our mobile app is in production; I now need a focused set of improvements completed: • Local data must be stored seamlessly when the connection drops, then pushed to the server automatically the moment the device reconnects. No manual triggers—users should never notice they were offline. • A compact dashboard page showing overall student performance (simple charts or progress indicators are fine) has to be added to the teacher section. Data sources and existing view-models are already in place. • Teachers also need a dedicated Attendance report. A clean list or table view filtered by class/date will do; exporting or printing is not required at this stage. • Replace the current username/password screen with Google Authenticator sign-in.

I need my existing Xamarin Forms mobile application fully migrated to .NET MAUI so it builds and runs flawlessly on both iOS and Android. The current codebase follows MVVM, uses Xamarin Essentials and local SQLite storage, and includes a few custom renderers; all of that functionality must remain intact in the new MAUI version. While you are inside the codebase, I also want to introduce two new capabilities: – Push notifications (FCM for Android, APNs for iOS) connected to the REST back-end that already emits notification payloads. – Email/password user authentication with secure token refresh, calling my existing API endpoints. Deliverables • A clean .NET MAUI solution that compiles in Visual Studio 2022 (or later) with signed Release builds for both i...

...Windows. The new app must behave identically to the existing one, so two core capabilities have to make the jump with zero regressions: • Push notifications – keep the same Firebase/APNs flows, badges, and deep-link handling. • Full Bluetooth support – both classic SSP (for legacy serial-port exchanges) and BLE (for modern GATT reads/writes and device scanning). I will hand over the entire Xamarin repo, current notification keys, and the Bluetooth service specs. I expect the MAUI project to build and run from Visual Studio 2022, produce signed packages for Android (AAB), iOS (IPA/TestFlight), and a Windows MSIX, and to follow best practices for dependency injection, platform-specific handlers, and Blazor component structuring. Deliverables 1. Source cod...
