About this gig
Looking for a high-performance React Native app?
I am a Full-Stack Engineer who builds scalable, production-ready apps for iOS and Android. Whether its a complex financial dashboard, a service marketplace, or a secure healthcare platform, I deliver clean code that scales.
I dont just build screens; I build systems. My background in Java concurrency and Node.js ensures your app is not only beautiful but fast and reliable under the hood.
What I offer:
- React Native Development (Cross-platform iOS & Android)
- Backend Integration (Firebase, Node.js, MongoDB)
- Performance Tuning (Fixing crashes, lag, and memory leaks)
- Custom UI/UX with smooth animations
- App Store & Play Store submission support
I have hands-on experience building apps like BudgetWise (finance tracking) and Constructaro (service booking), so I understand the complex logic required for real-world applications.
Why work with me? I focus on code quality and user experience. I handle the "hard stuff"like map integrations and complex state managementso you can focus on growing your business.
Please message me before placing an order so we can discuss your vision and ensure were a perfect fit!

FAQ
Will my app work perfectly on both iOS and Android?
Yes! I use React Native, which allows me to build a single codebase that runs natively on both platforms. This ensures your users get a consistent, high-quality experience regardless of the device they use, while also keeping your long-term maintenance costs lower.
What happens if my app gets rejected by the App Store or Play Store?
Don’t worry app rejections are common due to strict metadata or privacy guidelines.Because I’ve successfully deployed complex apps like healthcare and finance platforms, I know exactly how to fix these issues. If you choose my submission extra, I will work with you until the app is approved and live
Can you integrate a database or user login system?
Absolutely. As a Full-Stack Engineer, I specialize in connecting apps to secure backends. I usually recommend Firebase for real-time data and authentication or a custom Node.js/MongoDB setup if your app requires more complex logic. I'll ensure your data is secure and the sync is seamless.
Do you provide the full source code upon completion?
Yes, the source code belongs entirely to you. Once the project is complete and the order is marked as finished, I will provide a organized zip file or push the code to your GitHub repository. I believe in writing clean, well-commented code so any developer can easily work on it in the future.
