About me

I am an Android developer, currently interning at Doubtnut.

I am proficient in using MVVM Architecture and Jetpack Libraries such Kotlin Coroutines, Room, Navigation etc. in a project.

One of the major learnings I got from working on different projects is that "Execution is more important than Idea".
