About Steven Iveson

Steven Iveson, the last of four children of the seventies, was born in London and has never been too far from a shooting, bombing or riot. He's now grateful to live in a small town in East Yorkshire in the north east of England with his wife Sam and their four children.

He's worked in the IT industry for over 20 years in a variety of roles, predominantly in data centre environments. Working with switches and routers pretty much from the start he now also has a thirst for application delivery, automation, SDN, virtualisation and related products and technologies. He's published a number of F5 Networks related books, is a regular contributor at DevCentral and was an F5 DevCentral MVP for 2014.
