FAQ
Does my app need AI?
No. I develop React Native apps with or without AI features. If AI can genuinely improve your application's functionality or user experience, I'll recommend the most suitable solution based on your requirements.
Expo or bare React Native — which should I choose?
I recommend Expo for most new React Native apps because it simplifies development, builds, and updates. For projects requiring specialized native functionality or custom configurations, I can also work with bare React Native.
Can you upgrade my existing React Native app?
Yes. I can upgrade React Native and Expo SDK versions, update dependencies, fix compatibility issues, and help migrate older projects to the New Architecture where required.
Can I add AI features later?
Yes. I develop React Native applications with clean, modular code, making it easier to integrate AI features such as ChatGPT, Claude, Gemini, or other AI services in the future.
Can you convert my Figma design into a React Native app?
Yes. I can convert Figma, Adobe XD, or reference designs into responsive React Native screens for iOS and Android. If you don't have a design, I can also help create a modern, user-friendly interface.
Can you integrate Firebase, Supabase, and APIs?
Yes. I can integrate Firebase, Supabase, REST APIs, databases, authentication, push notifications, payments, and other third-party services based on your app requirements.
Can you publish my app on the App Store and Google Play?
Yes. I can assist with building, testing, and submitting your React Native app to the Apple App Store and Google Play Store. You'll need active developer accounts, and final approval depends on the stores' review processes.
Will I receive the complete source code?
Yes. You'll receive the complete React Native source code and ownership of the custom-developed work upon delivery, subject to any applicable third-party licenses.
