A Scala/Android developer at Wire, Berlin. I have never been a big fan of Functional Programming. I have come to appreciate Scala exactly because it allows me to be pragmatic and draw from both worlds, imperative and functional, as needed. I advocate healthy minimalism and keeping one's code clean and simple. I believe that in commercial applications these qualities beat high-level abstractions every time.
