Hussain Ali khan Maqpoon

Hi, I'm Hussain — a mobile & full-stack developer with 7+ years of professional experience building cross-platform apps and backend systems.

On the mobile side, I build with **Flutter and Dart**, using **BLoC/Cubit** for state management and **Firebase** (Firestore, Authentication, Cloud Storage, Cloud Messaging, Analytics, Crashlytics) for backend services. I've shipped production apps for real clients and personally handle Google Play Console publishing and release management.

On the backend side, I build **REST APIs in ASP.NET/C#**, including integrations with external systems like identity verification services and core banking platforms, backed by SQL Server, PostgreSQL, and MySQL.

I specialise in:
- Fixing bugs and adding features to existing Flutter apps, fast
- Integrating REST APIs and Firebase services into mobile apps
- Building ASP.NET backend APIs and database-driven systems
- Publishing and maintaining apps on the Google Play Store

I care about clean, working code and clear communication — I'll always give you an honest estimate before we start, and keep you updated as I go. Send me a message with what you need, and let's get it done.
