🚀 Flutter Developer | iOS & Android | Firebase • Booking • Healthcare
⭐ Top Rated on Upwork | 100% Job Success | 25+ Apps Published
Your app idea is sitting in a Google Doc right now — and maybe you have already been burned. A developer who ghosted you mid-build. Code nobody can maintain. An app that worked on the emulator and broke on a real phone. That stops here.
I am Fazil, a Flutter & Dart developer who builds cross-platform mobile apps for iOS and Android from a single codebase. One codebase. Two platforms. Faster launch, lower cost — and an app that actually works on launch day.
🔧 What I build
Booking & appointment apps (salons, services, real estate)
Healthcare & fitness tracking apps
On-demand & delivery apps (food, ride-hailing, home services)
E-commerce & marketplace apps
Real-time chat, live streaming & community apps
💻 Tech I work with daily
Flutter • Dart • Firebase • Firestore • BLoC • REST APIs • Stripe & payment gateways • Google Maps • Push notifications • Real-time chat • Custom admin panels
✅ Why clients stay with me
Scope agreed before day one — no surprise invoices
Tested on real devices before handoff, not just emulators
Clean, documented code your next developer can actually read
Full App Store & Google Play deployment — I don't leave you at the finish line
📦 Recent work
CarVault Pro — a full Flutter + Firebase car-maintenance tracker with push notifications and MOT reminders, designed, built, and shipped in 10 days. I've also delivered booking, tenant-screening, live-streaming, and chat-integration apps for clients worldwide — 5-star reviews across the board.
💬 Send me your app idea and your current timeline. Within 24 hours I will tell you exactly what it takes to build it — scope, time, and cost. No vague estimates.

Hi there 👋
Building mobile apps that ship on time and stay shipped. Senior mobile engineer with $200K+ earned on Upwork, 8,000+ hours delivered, and 30+ shipped apps maintaining 4.5★+ ratings on the App Store. Recent long-term retainer: 4,200 hours / $128K single contract at 5.0 stars. I've led small mobile teams on multi-year projects - setting up architecture, reviewing code, and onboarding new developers.
Industries I work across:
HealthTech · FinTech · AgriTech · Pharma E-commerce · Industrial IoT · Logistics & Delivery · Travel & Tourism · AI assistants · EdTech · Sports & Outdoor · Telecom · Entertainment · Lifestyle apps
What I deliver:
- Native iOS: Swift, SwiftUI, UIKit, Combine, Async/Await, Core Data, MVVM / VIPER, clean architecture

- Architecture & ops: scalable patterns, CI/CD pipelines, App Store Connect & Google Play submissions
How I work:
- First reply within ~4 hours, working hours
- Architecture decisions and POC inside the first sprint - never just "designs"
- 2-week trial sprint: scoped first deliverable, clean exit option after it ends - no long-term lock-in until we both confirm fit
- Long-term retainer preferred - most of my best work has been 6-month+ engagements
If you're scoping a new mobile app - iOS, Android, or cross-platform - let's chat. Share the brief and I'll come back with a scoped estimate plus first-sprint plan within 24 hours.
