Subscribe to our channel: youtube.pl/c/DevoxxPoland?sub_confirmation=1 You can write Haskell in any language. In this talk, I am going to show you how to do that in Kotlin. You will see a beautiful world without loops, variables, and other impure monsters. Instead, you will see monads that work on production. I will demonstrate how to create a useful functional framework for web applications. On top of that an insane linter that enables you to gradually enforce purity in your projects. Jarek Ratajski loves programming since his first line of code he did on the C64 in Basic. Somewhere in 90ties he's switched from C++ to java and spent next 20 years developing mostly Java software working for various companies and projects. Now he works for Engenius in Switzerland being Java/Kotlin developer during the days and Scala/Haskell open source hacker at nights.
