With over 30 years experience, I have been creating software for computers ranging from the Mainframe to the Mini (DEC PDP/VAX and Data General Nova/Eclipse) to the Micro (Windows, Macintosh and Z80 embedded systems). I have worked with large development teams as well as being the sole IT staff member. I have taken over existing software projects - implementing bug fixes, adding new features and moving to new platforms as well as implemented new projects - collecting user specifications, compiling development specifications for user approval and developing solutions. I am expert in taking user needs and implementing software solutions, be it a simple off the shelf solution or a custom software application.
