I've been working of dozens of Android apps. I've had a number of different roles: developer, senior developer, architect, engineering expert and consultant. Please see my Experience and Portfolio section to see more detailed descriptions.

I've got 3+ years of Kotlin experience. I've been experimenting with Kotlin even before Google announced it as a officially supported language on Android in July '17. When it became officially supported, I've started using Kotlin alongside Java on existing projects and writing Kotlin in new Android projects. I haven't only been using Kotlin for Android, I've also build RESTful API's using Ktor, a framework for building microservices and web applications in Kotlin. I'm aware of the advantages of Java over Kotlin and vice versa. Kotlin enables me to utilise functional-reactive paradigm, coroutines, extension functions, DSL builders and more on Android, which can't be done with Java 8. I've done 5+ projects which are now in production, using 100% Kotlin. Other than giving the developers possibility to write cleaner code, it also reduces crash rates with null-safety being a part of the Kotlin type system.

I've been working on iOS apps as a software architect and as a developer. Paired with my Android knowledge, I'm aware of advantages and pitfalls of both platforms, which enable me to approach problem solving from platform-agnostic standpoint.
