firebase backend

I am looking for a developer who can create a Firebase backend for my Flutter app. The main purpose of the app is to provide real-time updates to users, so I require a real-time database as a feature in my Firebase backend. Additionally, I need authentication and user management capabilities integrated into the backend. Finally, I would like to use Firestore as an additional Firebase service for my app. Ideal skills and experience for this job include experience with Flutter and Firebase, as well as proficiency in real-time database development.
