Generally: System & Application Architecture, Programming, and Project Management. I'm also frequently called upon as an advisor for ongoing projects, in order to give an outside perspective.

I have a broad range of experience, but I am particularly interested in enterprise integration (using middleware and data translation technologies), application porting (moving an application from one platform, like the AS/400 or mainframe, to another), low-level communications (TCP/IP & APPC), and programming in Java, C, and PHP.

If you are interested in porting an application from or to the AS/400 or mainframe, please contact me, as I have extensive experience in this area and would love to help.
