John Doak

I'm the person who is going to teach you techniques I've used to spend my days sleeping in switch closets at LucasFilm instead of typing in commands all day, or sipping tea in a sleep pod around Google, if you can avoid getting into that management thing I fell into. But if you want my professional resume, it is below:

John is the Principal manager of Layer 1 Reliability Engineering at Microsoft. Previously he was the manager of Physical Layer SRE and the Fleet Principal Automation SWE for Azure. His teams leads efforts around part serialization, data validation services and gating controls that enable Azure's datacenter operations. In addition to the mission of his team, John has led the development of Azure Data Explorer's Go SDK and the Microsoft Authentication Library for Go.

Prior to Microsoft, John was a Staff Site Reliability Engineer at Google. As part of the Network Engineering group he created their first network automation orchestration system, configuration/command abstraction systems and many of the automations that ran Google's backbone network. John led the migration of Network Engineering from Python to Go over several years, including the development of Go training classes at Google that have been taught around the world. He was a pivotal figure in the transformation of the network team at Google from a traditional network group to a network/systems group that later integrated with SRE.

Before his work at Google, he worked in the video game and film industry as a Network Engineer for LucasArts/LucasFilm/Industrial Light and Magic on franchises like Harry Potter, Marvel films, Pirates of the Caribbean and of course Star Wars.

John provides free video training classes for Go that can be found at www.golangbasics.com to help bootstrap new Go programmers. You can find his musings on Go and SRE topics at www.golangsre.com.
