I will integrate supabase or firebase into your flutter app
Oscar C
About this gig
You've built the Flutter UI now you need the backend to actually work. I'll wire up Supabase or Firebase so your app has real data, real users, and real-time updates.
I've integrated both backends across 4 published apps on the App Store, including a fintech savings platform, a fitness tracker, and an AI coaching app. I know where things break and how to set them up right the first time.
What I can integrate:
Authentication email/password, Google, Apple, phone
Database Firestore, Realtime DB, or Supabase Postgres
File storage images, documents, user avatars
Real-time data sync and listeners
Security rules and row-level security (RLS)
Push notifications via FCM
Edge functions and Cloud Functions
Not sure whether to use Firebase or Supabase? Tell me your use case and I'll recommend the better fit no upsell, just the right tool for the job.
Message me before ordering if your project has specific requirements. I'll confirm scope before anything starts.

Flutter developer focused on building clean, functional mobile apps for iOS and Android. I combine a strong product mindset with technical execution I don't just write code, I help turn ideas into features that actually make sense for users.
I've shipped 4 production apps on the App Store across fitness, fintech, nutrition, and AI coaching built with Flutter, Firebase, Supabase, and OpenAI integrations. Real apps with real users, not portfolio experiments.
I specialize in apps that are stable at launch: proper architecture, real error handling, and code you can maintain after delivery.

FAQ
My app already exists — can you integrate into existing code?
Yes, that's exactly what this gig is for. Share your repo and I'll review it before we start.
Firebase or Supabase — which should I use?
Firebase is faster to set up and great for real-time apps. Supabase is better for relational data and gives you more control. Message me and I'll recommend based on your specific use case.
Do I need to have a Firebase or Supabase account already?
No. I can set up the project from scratch and hand it over to you fully configured.
Will my data be secure?
Yes. Every integration includes proper security rules or RLS policies so only authenticated users can access their own data.
What do you need from me to get started?
Access to your Flutter repo (GitHub or zip), a description of your data models, and which backend you prefer (or let me recommend one).
