Martin Alfke is the co-founder and CEO of example42 GmbH. He has been a Puppet and automation enthusiast since 2007 and has delivered the official Puppet training in Germany since 2011. In the past, he would have said that he is a "System Administrator." Nowadays he prefers the term "Infrastructure Engineer." The big difference is that System Administrators SSH into systems, whereas Infrastructure Engineers fix their automation.
With example42 GmbH Martin supports Puppet Inc as Puppet Service Delivery Partner. He likes giving talks and workshops at conferences around the Globe.
