About me

I am an Australian Zend certified Development Director working at Mosaic in Brighton, UK with a passion for web application development and motorcycles.


I am the Development Director at Mosaic in Brighton, UK. Previously I have worked in London, Melbourne and Auckland for web development firms.

Currently I do most work in PHP , MySQL, JavaScript and more - of course. In previous projects I have employed C, Python, PostgreSQL, Oracle, MS SQL and many more.

I have written a book entitled Functional Programming in PHP, which helps the reader to understand functional programming within the context of a popular language that they know.

You can view my résumé or connect with me on LinkedIn.


I love motorcycles and pretty much anything else on wheels. Coding and programming problems fill up the longer and colder winter nights.


I am married with two children.
