What I built
- Flutter plugin for Android and iOS that reports root/jailbreak, emulator, debugger, hooking (Frida, Xposed), app tampering, proxy and VPN as separate findings with reason codes
- No single isSafe flag: the app collects observations and the backend makes policy decisions; failed checks report an error instead of passing silently
- Play Integrity and App Attest proofs bound to a single-use backend challenge and request hash, so they can’t be replayed for another transaction
- Native checks in Kotlin and Swift behind one Dart API, with screenshot blocking on Android and screen-capture detection on iOS

I'm a software engineer in Dubai who builds products end to end: cross-platform mobile apps in Flutter, the frontends people tap and click through, and the Node.js / NestJS backends that keep everything in sync.

Over 4+ years I've shipped apps to the App Store and Google Play across marketplaces, payments and retail, including some that talk to real hardware like Bluetooth receipt printers. I care about clean boundaries, predictable state (BLoC, Riverpod), offline-first data and boring, automated releases.

What I focus on

01
Mobile Apps with Flutter
Production Flutter & Dart apps for iOS and Android with BLoC, Riverpod, clean multi-tier layers and offline-first persistence with Hive & SQLite.
02
Backend & APIs
Node.js / NestJS services, REST & GraphQL APIs, real-time WebSockets with Redis pub/sub, and MongoDB, SQL & Firebase data layers.
03
Frontend & UI
Polished, responsive interfaces with custom widgets and Rive animations in Flutter, plus web frontends in TypeScript, JavaScript, HTML & CSS.
04
Native Integrations
Platform features through Method Channels: biometrics, secure storage and Bluetooth devices such as thermal receipt printers.
