About this gig
Senior Flutter Developer | AI SaaS Apps
Got an app idea but no technical team? I'll turn your vision into a launch-ready AI SaaS mobile app, no coding knowledge needed on your side.
I'm Abdullah, a Senior Flutter Developer with 5+ years building production-grade AI mobile apps for founders across the US, UK, and Canada. I don't write throwaway code. I architect apps your team can actually scale, using clean architecture with BLoC or Riverpod.
What you get:
- Cross-platform Flutter app running natively on iOS and Android from one codebase
- AI integration with OpenAI, Claude or Gemini
- Full Firebase backend (Auth, Firestore, Cloud Functions, Storage)
- Pixel-perfect UI from your Figma design
- Stripe payments
- App Store and Play Store deployment
- Source code always yours via private GitHub
Best fit for: AI SaaS founders building an MVP, startups needing a senior dev to ship fast, and non-technical founders who want a real partner, not just a coder.
Message me first with your app idea and timeline. I'll send a custom quote within 1 hour. Let's build something extraordinary.

FAQ
Will you provide the source code of the app?
Yes, 100%. Source code is yours from day one, delivered via a private GitHub repo with clean commit history. No vendor lock-in — you can hire any other developer to continue the work.
What will be the Price and Timeline for my project for flutter app?
Depending on the complexity, requirements, and particular demands of your project, different price ranges and time frames may apply. Let's talk and meet all with one meeting.
Do you customize existing flutter apps?
Yes. I can refactor messy codebases, migrate apps to clean architecture (BLoC or Riverpod), add new features, integrate AI capabilities (OpenAI, Claude, Gemini), and modernize old Flutter projects. Send me your repo and I'll review it free.
Do you deploy as well?
Yes. Premium package includes full deployment to both the App Store and Google Play Store. I handle Apple Developer setup, store screenshots, privacy policies, review responses, and the entire release process.
Can you redesign a Flutter app?
Absolutely. I redesign UIs to be pixel-perfect from your Figma or XD designs, while keeping or improving the underlying architecture. Modern UX, smooth animations, and responsive layouts for both iOS and Android.
What technology is Flutter built with?
Flutter is Google's open-source framework built with the Dart programming language. It compiles to native code on iOS and Android from a single codebase — giving you native performance, one team, and 40–60% faster development vs. building two separate apps.
Can my app have more than one language?
Yes. I implement full internationalization (i18n) and localization (l10n) in Flutter so your app supports multiple languages, currencies, RTL layouts (Arabic, Urdu, Hebrew), and region-specific formats. Common combos I've built: English + Spanish, English + Arabic, English + French.
What would I need to provide in order to get started?
ust three things to start: a brief description of your app idea, any designs you have (Figma, XD, or even rough sketches are fine), and your target timeline. If you don't have designs yet, I can recommend a designer or design them for you.
Can you develop AI-based mobile apps in Flutter or Native Android?
Yes. I specialize in AI mobile apps in Flutter. I integrate OpenAI (GPT-4o), Claude (Sonnet, Opus), Gemini, and custom LLMs for chatbots, AI agents, content generation, voice assistants, and computer vision. I can also do native Android (Kotlin) if your project specifically needs it.
Can you integrate OpenAI, Claude, or Gemini APIs into my Flutter app?
Yes. I've integrated OpenAI (GPT-4o), Claude (Sonnet, Opus), and Gemini into multiple production Flutter apps — including AI chatbots, AI agents, voice assistants, and content generation features. I handle the full integration: API setup, streaming responses, error handling, and cost optimization.
