Felix is a long-time Puppet user and contributor. He's been answering mailing list questions, bug reports and feature requests as well as StackExchange questions. He wrote a Puppet quick start guidebook in 2014 (available from Packt Publishing). These days he mainly tries to help with module maintenance, dabbles in some modules of his own and keeps building patches for the Puppet core. A Berlin resident of many years, Felix has a job in the trenches of puppetized IT operations.
