I’m a Flutter Engineer with 2+ years building scalable, production-grade cross-platform apps for Android, iOS, and Web. I own full product journeys end-to-end—from leasing and buying to post-purchase—alongside role-based enterprise tooling in a single real-estate super-app.

I’ve delivered real outcomes: 50K+ users, 10K+ monthly transactions with zero failures, and a 99.9% crash-free rate. I’m hands-on with scalable architecture and app optimization, taking features from design through Play Store/App Store deployment while keeping performance tight.

In my current role, I led development of the commercial leasing module and shipped a Flutter Web migration 2 weeks early while maintaining the 99.9% crash-free rate. I also built the property buying module with 3+ concurrent bookings, integrated UAE PASS & SIMS identity APIs for automated KYC, and cut manual onboarding by 80%.

I also focus on reliability at scale—processing transactions through CyberSource, reducing API latency by 30% with lazy loading, pagination, and Provider-based caching. I’ve automated releases with Codemagic CI/CD and Crashlytics monitoring, and I’ve delivered contract work and side projects that strengthen my reusable component libraries, performance habits (including Dart Isolates), and integrations-heavy development.
