Android Satta Matka App Development

I need an Android-only Satta Matka application built from the ground up. The end product must offer a smooth, secure Matka gaming flow with clean number selection, wallet handling, and automated result posting, all wrapped in a modern UI that follows current Play Store guidelines.

My initial scope includes:
• Native Android build in Kotlin or Java
• Real-time data sync (Firebase, Node.js, or similar back-end—open to your suggestion)
• Lightweight admin panel to manage games, results, and users
• User registration and login out of the box
• Push notifications once the core gameplay is stable

Deliverables
• Production-ready APK and Play-Store-ready bundle
• Complete, well-commented source code
• Admin console (web or in-app) with basic controls
• Deployment guide plus one week of post-launch bug-fix support

Acceptance criteria
• Stable on Android 8.0+ with no crashes in a 24-hour Firebase TestLab run
• Bets, results, and wallet balances update in under two seconds on a 4G connection
• Push notifications arrive even when the app is closed

If you have Matka or real-money gaming experience, a working demo will help me gauge fit, but it is optional.
