FAQ
Can you develop for Android, iOS, and Web?
Yes. I use Flutter app development to build cross-platform apps that work on Android, iOS, and Web from a single codebase, saving time and cost.
What is Firebase and why should I use it?
Firebase is Google’s mobile and web app platform that offers real-time databases, authentication, cloud storage, and analytics. It’s perfect for fast, secure, and scalable mobile app development.
Can you build apps with both online and offline features?
Yes. I can create offline-first Flutter apps with Firebase so they work without internet and sync data when online.
Which Firebase features can you integrate?
I can set up Firebase authentication, Cloud Firestore, Realtime Database, push notifications, analytics, and cloud storage — depending on your app’s needs.
Will you submit my app to Play Store and App Store?
Yes. I offer app store submission for Android and iOS as an optional service, including preparing all required assets and meeting store guidelines.
