Gilded Rose refactoring kata is a coding exercise designed to practice your refactoring and test cases writing skills. In this live coding session I will use the Kotlin version of the kata to show how a sequence of small improvements can make a difference taking program design to a better and more functional place. You will see a few refactoring heuristics, IntelliJ tips and tricks and design emerging from seemingly chaotic code.

Http4k is a lightweight HTTP library written in Kotlin that enables serving and consuming of HTTP services in a functional and testable way. Unlike many other libraries and frameworks which have complicated abstractions and workflows, http4k captures the essence of communication over HTTP with few simple concepts. In this session I will explain and demo the core concepts in http4k by live coding from scratch http server for noughts and crosses game.

Target audience: Software developers with couple years of experience using a programming language like Java, Kotlin or Scala.
