About this gig
Need Firebase added to your existing Flutter or Android app? I handle the full integration cleanly and correctly so you do not have to untangle it later.
I am a Senior Flutter and Android developer with 6+ years of experience. Firebase is in almost every app I have shipped including Hostrender, Amigo's Pizza, Lonch, and StoreFaces. I know every Firebase service deeply, not just the basics.
What I integrate:
- Firebase Authentication (email, Google, Apple, phone)
- Firestore real-time database with optimised queries
- Firebase Realtime Database
- Cloud Storage for files and media
- Push Notifications with FCM
- Firebase Crashlytics for crash monitoring
- Firebase Analytics and Remote Config
- Firebase Security Rules for data protection
Works with Flutter (Android and iOS) and Android Native (Java and Kotlin).
I write clean, scalable code and configure security rules properly so your data is protected from day one.
Send me your project details before ordering so I can confirm the integration scope and timeline.

FAQ
Do you work with existing apps or only new ones?
Both. This gig is specifically designed for adding Firebase to an existing app. Send me your project and I will assess how Firebase fits in without disrupting your current code.
Can you migrate my existing MySQL or SQLite data to Firestore?
Yes — the migration extra covers this. I will map your existing data structure to Firestore collections and handle the data transfer with no data loss.
Do you set up Firebase Security Rules?
Yes. Proper security rules are included in Standard and Premium. The Premium package includes a full security rules audit so your Firestore and Storage data is protected from unauthorised access.
Do you work with Flutter and Android Native?
Yes. I integrate Firebase into Flutter apps (Android and iOS from one codebase) and Android Native apps in Java or Kotlin. Tell me your stack when you message me.
Will the integration work offline too?
Yes. Firestore and Realtime Database both support offline persistence. I configure this by default so your users have a smooth experience even with poor connectivity.
