M Salman
About this gig
Your app looks good but nothing is connected yet? That is exactly what I fix.
I am Salman, a React Native developer who has shipped seven live apps running on Firebase and Supabase backends.
WHAT I SET UP FOR YOU
Email login, Google Sign In, Apple Sign In and OTP password reset
Firestore, Realtime Database or Supabase PostgreSQL with clean data models
Cloud storage for images, files and user uploads
Push notifications with FCM and Notifee that work in foreground, background and killed state
Real time chat, live updates and presence
Any REST API connected properly with loading, error and retry states
Security rules and row level security so your data stays protected
WHY THIS GIG
I work only in React Native, so integrations are done the right way, not patched
You get readable code, environment files and a short setup document
I test on real android and ios devices before delivery
Send me your app or repository and I will tell you honestly what is needed, how long it takes and what it costs.
Your users deserve an app that actually saves their data.

React Native developer (3+ years) building mobile apps with both CLI and Expo workflows. I specialize in Redux Toolkit state management, Supabase backend integration, Mapbox/geolocation features, and custom design systems with smooth native UI.
At SoftCircle, I worked on Teerex, an iOS golf community app, handling core feature development end-to-end. I write clean, maintainable code and deliver complete, production-ready solutions — not half-finished snippets.
Let's build something solid together. Message me with your project details!

FAQ
Firebase or Supabase, which one should I pick?
Tell me your features and budget and I will suggest one honestly. Firebase suits chat and notifications, Supabase suits relational data and SQL.
Can you work on my existing app?
Yes. Share a repository or zip file. I review it first and confirm the scope before you order.
Do you provide the backend cost too?
Both platforms have free tiers that cover most early apps. I will show you where the paid limits start.
Will push notifications work when the app is closed?
Yes. I configure foreground, background and killed state delivery, plus deep links from the notification.
Do you sign an NDA?
Yes. Send it before ordering and your code and data stay private.
