Flutter Engineer for Production Mobile Apps

I build Flutter apps that ship, get tested, and reach the stores. Most of my last five years has been production Flutter: fintech, consumer AI, blockchain wallets, and offline-first B2B tools. When a project genuinely needs native iOS, I reach for SwiftUI. The rest of the time Flutter is the right business call, and I treat it that way: real state management, real tests, real release pipelines.

The short version

Ali Wajdan is a senior Flutter engineer who ships production mobile apps for startups, not prototypes. He has built and released 15+ apps used by roughly 500,000 people, including Monetiza, a Flutter fintech app with 120,000+ users and a 4.8-star App Store rating, and DreamyBot, a Flutter AI app with 100,000+ users shipped by one engineer. He writes the Flutter app, the Node.js or FastAPI backend behind it, the RevenueCat subscription layer, and the App Store and Google Play release pipeline. His Flutter stack includes Dart, Riverpod, Firebase, Supabase, RevenueCat, native platform channels, and widget and integration tests. He works remotely from Lahore (GMT+5) with five hours of overlap with the EU and three with US-East, and takes either a remote full-time role or a fixed-scope project.

/ When to hire me

  • You need a Flutter app shipped to both stores, not a demo that stalls at TestFlight.
  • Your current app started in React Native and the UI work has become a tax.
  • You want one engineer who can also build the API and the subscription stack.
  • You need someone senior enough to pick the architecture and own the release.

/ What I build

  • Production Flutter apps for iOS and Android from one codebase.
  • State management that holds up (Riverpod or Bloc), not a pile of setState.
  • Subscriptions with RevenueCat and server-side receipt validation.
  • Offline state, push, deep links, and native platform channels when needed.
  • Widget, unit, and integration tests on the flows that earn money.
  • App Store Connect and Play Console submissions, review responses, and rollouts.

Common questions.

FAQ
  • Should my next app be Flutter or React Native?

    I've rewritten two production apps from React Native to Flutter and shipped both faster after the rewrite. Flutter's hot reload, widget composition, and rendering performance pay off after the first month. I'll pick React Native for a thin shell, but for anything with non-trivial UI it tends to become a tax.

  • Can you ship to both the App Store and Google Play?

    Yes, end to end. I handle App Store Connect, Play Console, signing, store metadata, review responses, and staged rollouts. I've shipped 15+ apps to both stores, including Monetiza (4.8-star rating, 8K+ reviews).

  • Do you handle in-app purchases and subscriptions in Flutter?

    RevenueCat with server-side receipt validation, never client-only. I shipped the subscription stacks for Monetiza (11x revenue growth in year one) and DreamyBot (4.7 on iOS). The Flutter-for-fintech post in /writing covers the architecture.

  • Can you build the backend too, or just the Flutter app?

    Both. I write the API in Node.js or FastAPI, wire up Firebase or Postgres, and connect it to the app. Most of my recent work has been the app and its backend together, which is the point of hiring one senior engineer for v1.

  • Are you available full-time or for a fixed project?

    Either. I take one remote full-time engagement at a time with a startup in the EU, UK, US, or Canada, and I also take fixed-scope Flutter projects (a build, a rescue, a store launch). Both get the same standard of work.

  • How do you keep Flutter code quality high while moving fast?

    Widget tests on the critical screens, unit tests on business logic, integration tests on auth and payments. I use Claude Code and Cursor daily to write those tests in the same loop instead of leaving them for later, and I review every commit.
