Flutter mobile appsfor iOS and Android

I build cross-platform mobile apps in Flutter and Dart — one codebase for iOS and Android — with Firebase, REST APIs, in-app purchases and AI features. When part of a product needs 3D, AR or realtime graphics, I bring in Unity, so each part is built with the right tool.

What I build: Flutter app developer

  • Cross-platform apps

    iOS and Android apps from one Flutter codebase, with clean architecture, smooth UI and fast iteration from MVP to v2.

  • Backend & accounts

    Firebase Auth, Firestore, storage, push notifications and REST APIs — plus admin panels so your team can manage content.

  • AI-powered features

    Chat assistants, smart search and generated content through LLM APIs such as OpenAI and Google Gemini, called securely from the backend.

  • Store launch & growth

    In-app purchases, analytics and crash reporting, then App Store and Google Play submission and updates.

FAQ

Questionsanswered

Flutter or Unity — which is right for my app?

Flutter is the better fit for business, social, productivity, booking and content apps with standard screens and forms. Unity is the better fit when the app is built around 3D, AR/VR, games or realtime graphics. I work with both, so I recommend based on the product, not the tool.

Can you build one app for both iOS and Android?

Yes. Flutter compiles one Dart codebase into native iOS and Android apps, which saves time and keeps both platforms in sync.

Can you add AI features to my Flutter app?

Yes — chat assistants, smart search, summaries and generated content using LLM APIs like OpenAI and Gemini, with API keys kept on the server and usage limits in place.
