Hey, this is Stan. What up? I'm passionate Android developer with more than 10 years of work experience. During the journey I met a lot of different technologies, built a number of project and figured it out well how to use Android SDK to its potential and bend to go beyond that. I came from Java and last 7 years Kotlin is my main programming language. I love writing more functional and reactive code, using Kotlin immutable classes, Coroutines and Reactive Extensions. I have a preferred stack of technologies and ready to go solutions for common problems such as client-server communication, data persisting, offline cache, navigation and more, but do not doubt I will find a solution for your problem too.
