Flutter mobile app development
I’m Felice Zingaro, a Flutter developer based in Andria, in southern Italy. I design and build iOS and Android apps from a single codebase, together with the backend and integrations they need, and see them through to store release. I work remotely with clients across Italy and abroad.
The problem
A native iOS app and a native Android app are two codebases to write and maintain. With Flutter there is one app. But the app is only the visible part: behind it there is almost always a backend, payments, notifications and a dashboard where the people running it manage content and users.
How I work
- AnalysisWhat the app must do, for whom, with which screens, and what it needs behind it: backend, payments, integrations with systems that already exist.
- App developmentA single Flutter codebase for iOS and Android, and for the web when a dashboard is needed.
- Backend and integrationsAPIs and databases, sign-in with email, Google or Apple, Stripe or PayPal payments, push notifications, real-time data over MQTT, links to WooCommerce.
- ReleasePreparing and submitting to the App Store and Google Play.
- MaintenanceUpdates for new iOS and Android versions, fixes and new features.
Time and cost
Every project gets its own estimate. Time and cost depend mainly on:
- how many screens and features the app has;
- whether it needs a new backend or connects to existing systems, such as an online store or ERP;
- payments, notifications, Google or Apple sign-in, real-time features;
- whether a web dashboard is also needed for managing content and users;
- maintenance after release.
