FAQ
: Do you build apps using Expo CLI or React Native CLI?
: I primarily build using Expo, as it allows for rapid development, smoother testing, and streamlined over-the-air updates. However, if your project requires custom native modules that require React Native CLI, I can absolutely build using that workflow instead. Let's discuss your requirements!
Can you convert my existing business website into a mobile application?
Yes, absolutely! I can convert web to app seamlessly by wrapping your responsive website into a highly optimized React Native app. It will feel like a native Android application, look professional, and be fully ready for the Google Play Store.
What do you need from me to start working on my Firebase app?
To build a complete Firebase app, I will need your app requirements, any design files/wireframes you have, and temporary access to your Firebase console so I can configure user authentication, the database, and cloud storage securely.
Can you implement real-time push notifications?
Yes! I specialize in setting up FCM push notification systems (Firebase Cloud Messaging). I will handle the configuration on the backend and integrate it into your React Native frontend so you can send targeted alerts directly to your users' Android devices.
How will I be able to test and preview my app during development?
I provide regular milestone updates and secure APK delivery. You will be able to download the APK file directly to your personal Android smartphone to test the layouts, buttons, performance, and overall user flow in real time.
Will you upload my finished application to the Google Play Store?
App submission is included in my Premium package! I will handle the technical release management—including generating the optimized production AAB file, setting up store assets, and submitting it for review. Note: You must provide your own Google Play Developer account.
Will the app work on all versions of Android and different screen sizes?
Yes, your app will be built using responsive design principles. I ensure full compatibility across various screen sizes (phones and tablets) and test it thoroughly on modern Android versions to guarantee smooth performance
Do you provide the complete source code after the project is completed?
Yes, 100%. Once the project is completed and approved, I will deliver the complete, cleanly structured React Native source code. The code will be well-commented and organized according to industry best practices so it is easy to update in the future.
