    • Briefly worked on a Xamarin Forms based mobile app which is used by pickup dry cleanings. Made a beautiful Circular menu.
    • Built from scratch an automatic fuel pump payment mobile application in Xamarin Forms. Used MVVM Cross to make the code highly maintainable; the user can pay for fuel via this app at a gas station.
    • Developed a POS system to be used at a gas station which involves complex socket programming with security for card payment.
    • Implemented mobile push notifications using OneSignal.
    • Integrated a real-time fuel server with a custom TCP protocol with a POS system that will be used by various gas stations to enable payments via credit/fleet cards. The POS system was developed by me. The unique feature is that the app supports multiple languages simultaneously i.e., it could show both Arabic and its English translation at the same time.

  • Music Player

    A Xamarin Forms-based application. Most of the front end was done by me. My contribution in the back end was limited to this four-member project.

    The media player was similar to the amazon music app however was different in many aspects. Due to the impact of COVID-19, the project was ultimately scrapped off just before publishing.

    Due to the nature of the app, I had to create custom plugins from scratch most of the time. This includes a custom navbar, custom iOS wheel slider on Android. Unique curved slider and more.

  • Mobile Application for Fueling

    I developed this white-label application for a Canadian client; it automates the process of pumping fuel from the gas station. Based on a current location, it detects gas stations where payment could be made using the app.

    This Xamarin Forms-based app is available on the iOS and Android platform

  • Mobile Application | Boardroom Portal (Aprio)

    This large Xamarin Forms app runs on Windows, iOS, and Android platforms; it took eight months to build this app.

Besides actively participating in designing and building of the drone, I also handled the integration and PID controller tuning part.
