OpenStack Nova, QA, and the Gate in general
Sean Dague is a contributor across a wide variety of projects to OpenStack, a core reviewer on Devstack, Tempest, Grenade, Nova, and lots of smaller projects. He was the QA PTL for the Havana and Icehouse cycles, and you'll often see him trying to get to the bottom of an interesting race condition exposed in OpenStack in the integrated testing gate.
Sean has been working in Open Source as part of his job for over a decade, currently as part of the Cloud team at IBM. He was previous part of Samsung's Open Source Group, and IBM's Linux Technology Center, and Hewlett-Packard.
Sean has been an avid Linux and Open Source user and contributor going back to college days. He created the Mid Hudson Linux Users Group in 2003, and has been running a monthly Linux and Open Source lecture series there ever since, exposing hundreds of people to the joys of Open Source technology.
