I've been building apps on Android for more than 5 years. My current technology stack consists of Kotlin, Dagger, RxJava/Coroutines and Room. I also have a background in backend development solutions (APIs and admin panels) using PHP and Java.
Demo apps demonstrating use of Kotlin, MVVM pattern and some popular libraries:

In my free time I like playing Smashing Four.
