I’m a Developer Educator with cloud communications platform Twilio for its wireless and Internet of Things division. Previously, I spent six years as the Senior Tech Writer and a Project Manager at IoT platform-as-a-service company Electric Imp.

Before that, I was a technology journalist, 13 out of 25 years spent in senior roles on the website The Register. At other times I contributed to a wide array of publications and news organisations, including The Times, The Guardian, The Independent, the BBC and CNN.

This site is dedicated to assorted programming projects I’ve worked on over recent years.
