• Dennis Brouwer Sr. Java Tester
  For everything that needs to be tested in some way, Dennis is the guy to go to. He likes to tune servers and systems to the max by tweaking them over and over again and not letting a system rest before every button has been tried and every wheel has been turned. Give him an app and eventually smoke will come out of it. Apart from this, Dennis monitors overall system performance, keeps a close eye on naming consistency for artefacts in our main DB, sets up our development and beta environments, prepares scripts for hardware or service migrations and, last but not least, participates in the development process with a little Java programming here and there. Is there anything Dennis doesn’t do?
