I will develop a cross platform mobile app with react native and expo


About this gig
Have an app idea, a Figma design, or a half-finished React Native project?
I'll turn it into a polished app that runs on both iOS and Android from a single codebase.
I'm Sahan, a full-stack developer with 3+ years of experience building production web and mobile apps with React Native, Expo, Node.js, Python and PostgreSQL so I can build your entire app, backend included, without you hiring a second developer.
What you get:
- Pixel-perfect UI from your design (or I'll design clean screens for you)
- Login & secure authentication (JWT, Google/Apple sign-in)
- API & backend integration or a custom backend built for you
- Push notifications, payments, maps, camera & real-time features
- Store-ready builds for App Store & Play Store
What you can expect:
- Full source code ownership
- Daily progress updates you're never left wondering
- Clean, documented code another developer can maintain
- Honest scoping before I start. No surprises.
- Also happy to fix bugs or add features to your existing React Native app.
- Message me with your idea and I'll reply within the hour with a clear plan.

FAQ
Will the app work on both iPhone and Android?
Yes. React Native uses one codebase for both platforms, which saves you roughly half the cost of building two native apps.
I only have an idea, no design. Can you still build it?
Yes. I'll create a clean, modern UI based on your description and reference apps you like.
Do you build the backend too?
Yes. I build complete backends with Node.js or Python (Flask/FastAPI) and PostgreSQL/MongoDB, including admin dashboards if needed.
Can you publish the app to the App Store and Play Store?
I deliver store-ready builds and can guide or handle submission as a gig extra. Note: you'll need your own developer accounts (Apple $99/yr, Google $25 one-time).
Do I own the source code?
100%. Full code, repo access, and documentation are yours on delivery.
Can you work on my existing React Native app?
Absolutely — bug fixes, new features, upgrades to the latest RN/Expo version, and performance improvements.
