FAQ
Can you develop both Android and iOS apps?
Yes. I specialize in cross-platform mobile app development using Flutter, which means your app will work on Android, iOS, and even Web from a single codebase.
What is an offline-first app?
An offline-first app works without an internet connection and stores data locally using SQLite or similar databases. When internet becomes available, it syncs with an online database like Firebase or Supabase.
Which technologies do you use for app development?
I mainly use Flutter app development for cross-platform apps, along with Firebase, Supabase, and SQLite for database solutions. I can also work with FlutterFlow or Figma for rapid prototyping.
Can you publish my app to the App Store or Play Store?
Yes. I offer app store submission for both iOS and Android as an optional service. This includes preparing all required assets, descriptions, and helping meet store guidelines.
Can you integrate AI features in my app?
Yes. I can add AI mobile app development features like chatbots, text recognition, or predictive analytics to enhance your app’s functionality.
