flutter and firebase realtime DB

I am looking for an expert Flutter developer with experience in Firebase Realtime Database. The project requires real-time data syncing and integration of push notifications. The client already has a complete design for the app, so assistance with design is not needed.

Ideal Skills and Experience:
- Expert level experience in Flutter development
- Strong knowledge of Firebase Realtime Database and push notifications
- Ability to seamlessly integrate real-time data syncing functionality
- Attention to detail and ability to work with a pre-existing design
