James is currently working as a Software Engineer providing large scale Warehouse Management Systems and Airport Baggage Handling Systems. He is a Windows specialist but nowadays spends about 65% of his time fighting with VI in a vain attempt to get his UNIX C code to compile. He has been programming in C/C++ for 6 years and Visual C++/MFC for 4 years.
In his spare time James plays a variety of musical instruments including guitar and piano with varying degrees of success. He has been told he spends too much time and money in the pub but doesn't everyone have their own stool at the bar?
James is originally from Nottingham (no Robin Hood jokes please) but is now based in sunny Manchester, UK.
The attached photo shows James in his favourite position, drinking beer with a hand growing out of his neck.
