• Cross-platform Flutter app (iOS + Android from a single codebase)
• Clean architecture with proper state management (BLoC, GetX, or Provider)

Looking forward to hearing about what you're building.

Job Success
Islamabad, Pakistan - 8:50 am local time
Most of my clients come to me with one of three problems:
(1) they have a designer's mockup and need it built right the first time,
(2) they have a half-finished app that needs to be fixed and shipped, or
(3) they need to add real-world features like payments, push notifications, or offline sync to an existing build. I handle all three.
What I build:
- Cross-platform mobile apps in Flutter (iOS + Android from one codebase)
- Firebase-powered backends: Auth, Firestore, Cloud Functions, Push Notifications
- Payment integrations with Stripe and in-app purchases
- REST API integrations and custom backend connections
- State management done right with BLoC, GetX, or Provider
- App Store and Play Store submissions, end to end
Why clients hire me again:
Clean, maintainable code you can hand to the next developer without embarrassment
I write tests, document what I build, and don't disappear after delivery
Honest timelines — if your idea is a 6-week build, I'll tell you, not promise 2 to win the job
Send me a message with your project details and I'll get back to you within a few hours with honest feedback on scope, timeline, and approach.
