Preferred field

The most interesting fields in information technology are those closest to technology. My primary interest is in software development and design. Consultancy can be offered on a broad range of information technology topics. A special focus is on process consultancy, software development, open source and Java/J2EE

Although in the past I have successfully fulfilled the role of team leader and project manager, my interests lie with more technical roles.
