Jérôme Petazzoni

Jérôme is a senior engineer at Docker, where he rotates between Ops, Support and Evangelist duties and has earned the nickname of “master Yoda”. In a previous life he built and operated large scale Xen hosting back when EC2 was just the name of a plane, supervised the deployment of fiber interconnects through the French subway, built a specialized GIS to visualize fiber infrastructure, specialized in commando deployments of large-scale computer systems in bandwidth-constrained environments such as conference centers, and various other feats of technical wizardry. He cares for the servers powering Docker, helps our users feel at home on the platform, and documents the many ways to use dotCloud in articles, tutorials and sample applications. He’s also an avid Docker power-user who has deployed just about anything on Docker – look for one of his many custom services on our Github repository.
