Android app changes for kotlin code

I'm looking for someone to help make changes to an Android app written in Kotlin code. I need someone who is familiar with version 1.0 of the language. My app needs some existing code and potentially UI designs changed to implement some new features. The changes will require part of the UI design to be updated, but other parts may remain the same. If you think you have the expertise to make these changes, please get in touch. Name of the app is Winzy - www.winzy.in . Some animations required to be added to game play as attached
