Johan is one of the Akka Team developers at Lightbend, keeping the actors acting, the cluster clustered and the streams streaming. He's a big Scala fan and has been working with tech on the JVM platform the last 10 years. He's a co-organizer of Scala Usergroup Stockholm. Talk to him about Akka things - Actors, Streams, distributed systems (obviously), Scala, extreme music, bicycle accidents and bouldering, or anything you like actually.
