In my current Senior Mobile App Developer role, I develop secure native Android applications using Kotlin, Jetpack, and clean MVVM architecture. I integrate GraphQL and REST services and manage local data with Room, SharedPreferences, and Keystore.
I also integrate payment gateways including TAP, Checkout, and Lean, and use Amplitude, Firebase Analytics, and CleverTap for analytics and logging. I support releases across Staging, QA, Demo, and Production, including distribution through Firebase App Distribution and Google Play Store.
On Ministry of Hajj & Umrah Projects, I developed native Android and iOS applications as well as a Flutter application. I worked with TIBCO REST APIs and MQTT for live messaging and map data, and published apps to the Apple App Store, Google Play Store, and secure enterprise channels.
Earlier, I developed iOS applications including the Jahez app, where I refactored the UI and code structure and implemented features in Objective-C and Swift. I also supported ERP and Oracle 10g database administration and contributed to an attendance system integrated with ERP.
