Refactored the existing code and architecture to proper MVVM patterns.
Implemented a Bluetooth IOT device connection in real time.
Updated over-air IoT device firmware using Bluetooth from the app.
Completed the gradual migration of Xamarin.Forms to .NET MAUI.
Ensured the project remains HIPAA compliant throughout its lifecycle.
Introduced Agile methodologies and automated build using AppCenter. Here's the link to the app: Apps.apple.com/us/app/zibrio-balancecoach/id1452909451.
Created an internationalized cross-platform native application in Xamarin.Forms which is available in Android, iOS and Windows platform. Extensively worked with PDFTron SDK to accommodate a full-blown pdf editor inside the app.
Briefly worked on a Xamarin.Forms-based mobile app which is used for 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 to enable payments via credit/reward cards for gas stations across Canada. The unique feature is that the app supports multiple languages simultaneously.
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.
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
This large Xamarin Forms app runs on Windows, iOS, and Android platforms; it took eight months to build this app.
