🚀 Flutter Developer | Debugging Specialist | Firebase + Laravel | Production App Support

Every Flutter Developer can build an app.

But not every Flutter Developer helps you after the app is published.

That is where many clients face the real problem.

The app is live, users start using it, bugs appear, API issues happen, Firebase notifications fail, iOS has a build problem, Android behaves differently, subscriptions do not validate, or the UI does not feel smooth anymore.

I am here to help with that full journey — not only building the app, but also testing, debugging, improving, publishing, and supporting it after launch.

I build Android and iOS apps using:

✅ Flutter
✅ Dart
✅ Firebase
✅ Laravel REST APIs
✅ Push Notifications
✅ Payments / Subscriptions
✅ App Store + Google Play deployment
✅ AI-assisted development tools

My strongest specialty is debugging.

I enjoy finding the real reason behind a problem. I do not just guess and change random code. I check logs, test step by step, compare Android and iOS behavior, inspect API responses, review state management, and fix the actual issue.

If your app is already built but something is broken, slow, unstable, or not ready for release, I can help.

🤖 AI-Assisted Development
I use modern AI tools for planning, UI iteration, debugging, code scaffolding, and faster development.

But I do not blindly trust AI-generated code.

I review it, test it, clean it, and make sure the final app is maintainable.

### 💡 Why Clients Work With Me

I understand that most founders and small businesses do not just need “code.”

They need someone who can take an idea, understand the business goal, build the app, connect the backend, test the flow, publish it, and help when things break later.

That is how I work.

✅ I think like a product builder, not only a coder
✅ I communicate clearly
✅ I work with milestones
✅ I can work on new apps or existing codebases
✅ I support testing and launch
✅ I focus on practical solutions
✅ I use AI tools to move faster but still code manually when needed

### 📦 Apps I Can Help Build

As a Flutter Developer, I can work on:

🛒 Marketplace apps
🍽️ Restaurant ordering apps
🧾 POS/order management apps
🏷️ Auction apps
🛍️ E-commerce apps
💬 Social apps
🔐 Security apps
🤖 AI-powered apps
📍 Location-based apps
💳 Subscription apps
📊 Dashboard/admin-connected apps

### 🧠 My Working Style

First, I understand the problem.

Then I create a clear plan.

Then I build, test, fix, and deliver.

For debugging work, I usually follow:

Reproduce the issue → check logs → trace the flow → find root cause → fix → test again

For new app development, I follow:

Requirement → UI → backend/API → testing → deployment

Simple. Practical. Reliable.

### ✅ Best Fit For You If

* Build a new MVP
* Fix an existing Flutter app
* Connect Firebase or Laravel APIs
* Improve performance
* Clean up UI
* Fix bugs before launch
* Submit your app to App Store or Google Play
* Support the app after publishing

If you need a Flutter Developer to build, fix, improve, or launch your mobile app, invite me to your job.

I will review your requirements and give you a clear next step. 🚀
