If you've ever hired a developer who disappeared mid-project, missed a deadline, or delivered something that looked nothing like what you discussed, you already know how expensive the wrong choice is.
I'm Hassan. I've shipped production Flutter apps for iOS and Android across 5+ years and multiple industries, from first commit to App Store and Play Store approval. My 100% Job Success Score on Upwork isn't a lucky streak. It's the result of one habit: I treat your product like it's mine.
What I've built:
➤ Cross-platform iOS & Android apps from a single Flutter codebase, used in production across e-commerce, HR tech, field operations, and social platforms.
➤ Firebase & Supabase backends, including Auth, Firestore, Realtime Database, Cloud Functions, and FCM, along with clean REST API integrations with third-party services.
➤ E-commerce and marketplace apps with Stripe and in-app purchase integration. Clients have gone live and processed real transactions from day one.
➤ Attendance, HR, and productivity tools with role-based access, offline sync, and real-world field use.
➤ Social and community apps with real-time chat, push notifications, and media handling.
➤ I've navigated App Store rejections, Firebase quota limits, and Play Store policy disputes and shipped anyway. I know the edge cases that cost less experienced developers weeks.
How I work:
➤ Clean architecture from day one using BLOC, Provider, or Riverpod, so your codebase stays maintainable long after I'm done.
➤ 0–4 hour response time, 6 days a week. You will never wonder where I am.
➤ Plain English communication, honest timelines, and problems flagged early, never at the deadline.
What clients say:
➤ "Hassan Zafar is an amazing person. Done the job successfully before time." — Upwork client
➤ "The project was completed efficiently and within the expected timeframe. He was responsive and available to provide clarification." — Upwork client
If you have a project or even just an idea, send me an invite. I'll give you an honest scope and timeline assessment within a few hours, not a sales pitch.
