Android-to-MAUI App Port

I need my production-ready Android app ported to .NET MAUI so it runs smoothly on both Android and iOS. The MAUI version must mirror the current design; no redesign is required—just replicate the existing screens and flow.

Key features to carry over
• User authentication handled through Firebase Auth
• Push notifications delivered via Firebase Cloud Messaging

Scope of work
• Create a clean .NET MAUI solution targeting Android and iOS
• Migrate all authentication logic and token management to Firebase within MAUI
• Implement cross-platform push notification handling, including permission prompts and background delivery
• Reuse existing business logic where feasible; rewrite only the platform-specific pieces
• Ensure builds compile in Release mode and run on real devices and emulators for both stores

Deliverables
• Complete source code in a Git repository
• Build-ready APK and IPA (or TestFlight package)
• README with setup, build, and basic test instructions
• Pixel-perfect UI parity with the current Android app
• Verified login/logout flow and successful reception of test notifications on both platforms

Acceptance criteria
1. App launches, authenticates, and navigates exactly like the Android reference.
2. Push notifications are received when app is foreground, background, and terminated.
3. No unexpected crashes or UI glitches on recent Android and iOS versions.

If you have prior experience shipping .NET MAUI apps with Firebase integration, I’d love to see a couple of examples and hear your estimated timeline.
