Nathaniel Felsen is a DevOps engineer who started working on DevOps engineering concepts over 10 years ago, before the term was even coined. He worked in several companies ranging from small start-ups to enterprises, including Qualys, Square, and more recently, Medium. Outside of work, Nathaniel lives a fabulous life where he enjoys running after his very active kids and spending a fortune on occasional date nights with his wife. Although Nathaniel is French, he prefers exploring local stout beers with friends than drinking wine. He holds a MS degree in system, network, and security from Ecole Pour l'Informatique et les Techniques Avancées (EPITA), a top CS engineering school in France.
