Sebastiaan Tammer is a Linux enthusiast from the Netherlands. After attaining his BSc in information sciences, he graduated with an MSc in business informatics, both from Utrecht University. His professional career started in Java development, before he pivoted into a Linux opportunity. Because of this dual background, he feels most at home in a DevOps environment.
Besides working extensively with technologies such as Puppet, Chef, Docker, and Kubernetes, he has also attained the RHCE and OSCP certificates. He spends a lot of time in and around Bash. Whether it is creating complex scripting solutions or just automating simple tasks, there is hardly anything he hasn't done with Bash!
I would like to thank my girlfriend, Sanne, for all the help and support she has given me throughout the years. She has had to endure the late nights studying, me fixing stuff (which I had inevitably broken only hours earlier), and my endless storytelling about all those exciting new technologies. Thanks for the enormous amount of patience and love. I could not have done it without you!
