At PayChoice Multi International, I’m the primary mobile engineer for the PayChoice payment-services app and related products, including Member360 and GymLeads Companion / FrontDesk. I built the REST network layer and integrated secure multi-provider payments, FCM notifications, and real-time map features.

At Moltaqa (MolTaqa), I built and shipped products including GASC, Mal3bko, and HMF, and designed a reusable base-component and networking layer for white-label variants. I also handled store operations and migrated legacy React Native functionality to Flutter; across my mobile development work, 40+ applications were published to Google Play and the App Store.
