Work Experience

Android Developer at Comwave Institute

February 1, 2020 - Present

Working as an Android developer, I created my first app using Java, which was a simple POS system for petrol pumps. I developed the app from scratch and learned to create APIs in ASP.NET. I transformed legacy Java apps into Kotlin-based solutions improving code readability and maintainability. I collaborated with backend teams to integrate RESTful APIs to ensure efficient data exchange. I introduced caching strategies to minimize network requests, reduce latency, and enhance app performance. Utilized Kotlin Coroutines for asynchronous tasks while employing MVVM architecture to separate concerns. Used Retrofit for network communication and Glide for image loading.

Software Development Intern at Telenor Pakistan
