Konrad is a late-night passionate dev living by the motto "Life is Study!", working on the Akka project at Lightbend. He also contributed most of the current Reactive Streams TCK, and maintains various other open source projects. His favourite discussion topics range from distributed systems through performance tuning, benchmarking and capybaras. He has founded and run multiple user groups (Java, Scala, Computer Science, ...), and is co-leading the successful GeeCON conference. In those rare times he's not coding, he spreads the joy of computer science by helping local user groups and whitepaper reading clubs. He also holds number of titles, the silliest of them being Java One RockStar.
