I will do mobile app development react native flutter ios android ai app developer


Sobre este Serviço
Need a custom mobile app that works on both iOS and Android? I'll build it using React Native/Flutter.
I'm Sumit, 14+ years experience, 50+ projects delivered including dozens of mobile apps across fintech, e-commerce, healthcare, food delivery, on-demand, and social networking.
React Native lets me build one app that runs natively on both platforms. Faster delivery, lower cost, consistent experience on every device.
What I build:
- Custom mobile apps for iOS and Android
- Clean, modern mobile UI with native animations
- User auth, profiles, and role management
- Push notifications and real-time chat
- REST API and backend integration
- Camera, location, maps, and device features
- Payments via Stripe and in-app purchases
- Firebase for analytics, storage, and auth
Need a backend too? I build full stack mobile apps with Node.js, Express.js, and MongoDB.
Why work with me:
- I personally lead every project with a dedicated senior mobile developer
- One codebase, two platforms, faster delivery
- App Store and Play Store submission support
- Clean, maintainable code built to scale
- Post-delivery support included
Message me with your app idea before ordering.

Perguntas frequentes
Who will work on my mobile app development project?
I personally lead every React Native mobile app project. I assign a dedicated senior mobile app developer from my team, and I oversee code quality, testing, and communication throughout.
Q: Do you build mobile apps for both iOS and Android?
Yes. I use React Native to build cross-platform mobile apps with a single codebase that runs natively on both iOS and Android. One mobile app, both platforms, lower cost.
Can you also build the backend for my mobile app?
Yes. I build full stack mobile apps using Node.js, Express.js, and MongoDB for the backend. REST APIs, database, user authentication, and deployment all included.
What kind of mobile apps can you build with React Native?
I build e-commerce apps, food delivery apps, on-demand service apps, social networking apps, fintech apps, healthcare apps, booking apps, and custom mobile applications for any industry.
Will my React Native mobile app feel like a native iOS and Android app?
Native renders native components, so your mobile app will have smooth animations, fast performance, and a native look and feel on both iOS and Android devices.
Do you help with App Store and Play Store submission?
Yes. I assist with preparing your mobile app for submission to both Apple App Store and Google Play Store, including screenshots, app descriptions, and build configuration.
Can you integrate push notifications in my mobile app?
Yes. I integrate push notifications using Firebase Cloud Messaging for both iOS and Android. I also build in-app notifications and real-time messaging features for mobile apps.
How long does custom mobile app development take?
A starter mobile app with 3 screens takes about 7 days. A feature-rich mobile app with auth and API takes 14 days. A complete mobile app with backend and store deployment takes around 30 days.
Do you provide the mobile app source code?
Yes. You get full ownership of the complete React Native mobile app source code. Clean, documented, production-ready code that your team can maintain and scale.
Can you work on my existing React Native mobile app?
Yes. I can add features, fix bugs, improve performance, or redesign your existing React Native mobile application. Send me access and I'll review your mobile app codebase first.
