With over 32 years of commercial IT you can be sure that I have plenty of real world experience to help you out. Focusing mainly on XML technologies but have found that I can help wherever there are problems to be solved.


I know how to solve problems, being able to break a situation down to its constituent parts. Its not magic, although it often seems that way.


If you need some bespoke programming then I'm the one for you. I'm always learning new technologies and take pride in being able to separate the wheat from the chaff.
