I will develop a mobile app with react native for android and ios


About this gig
Looking for a developer who can take your idea and ship a real, store-ready app not a half-finished prototype? You're in the right place.
I'm a senior full-stack & mobile developer with 16+ years of experience and multiple apps published live on the Google Play Store. I build fast, clean, cross-platform apps with React Native + Expo, so you get both iOS and Android from a single codebase.
What I can build for you:
- User authentication (email, OAuth, JWT)
- Payment & subscription integration (Stripe, RevenueCat, in-app purchases)
- Push notifications (Firebase Cloud Messaging)
- Real-time features chat, live tracking, updates
- REST / GraphQL API integration with your backend
- Smooth, responsive UI built to Apple Human Interface Guidelines
- App Store & Google Play submission
Why work with me:
- 16+ years shipping production web & mobile software
- Real published apps I can show you (links on request)
- Clean, maintainable, well-documented code
- AI-assisted workflow for faster delivery without cutting quality
- Clear communication and on-time delivery
Message me before ordering with your idea so I can confirm scope and timeline. Let's build something people actually want to open every day.

FAQ
Will my app work on both iPhone and Android?
Yes. I build with React Native + Expo, so one codebase runs on both iOS and Android.
Can you publish the app to the stores for me?
Yes — store submission is included in Standard and Premium. You'll need your own Apple Developer and Google Play accounts (I'll guide you through setup).
Do you build the backend too?
Yes. I'm full-stack (Node.js, PostgreSQL, Firebase, Supabase), so I can build the app and its backend together.
I already have a designer / Figma file. Can you build from that?
Absolutely. Send me your designs and I'll build the app to match precisely.
Can you add AI features?
Yes — AI chat, recommendations, and smart features can be added. Message me to scope it.
