About Me

Me, running. I like to run.

I was born in the Yorkshire town of Holmfirth, a place most famous for BBC sitcom Last Of The Summer Wine - I am adept at riding down a hill in a bathtub.

I attended Holmfirth High School from 1985-90. I sat A-Levels at Greenhead College in Huddersfield before studying at Edge Hill College, Ormskirk 1992-1995. After a brief career as a journalist and writer, I attained a Master's degree in Designing Worldwide Interactive Systems from the University of Huddersfield in 1999.

I've lived in London since 2000, during which time I've worked as a Designer, Web Developer, Software Engineer and Technical Lead for Capital Radio Group, GCap Media PLC, BBC Worldwide, EMAP Automotive, Global Radio, Sainsbury's and Ocado.

I'm from a design and front-end background and have worked with HTML, JavaScript and CSS since 2000. For a few years I built a lot of games in Macromedia Flash with ActionScript.

In 2006 I started working with Python using the Django framework. I've worked with most iterations of the framework from 0.96 onwards.

In 2016 I moved to work at Sainsbury's and developed microservices using Python and Go Lang.

My work at Ocado is mainly focussed on building developer tools for working with AWS.

I've run development teams and line-managed developers since 2006.
