I hired Karl to work on some complex software for us on a new platform. He did this with enthusiasm and dedication. I was particularly impressed by the way he was able to document the system architecture for our group - some of his written materials remained the basis of explanation of the area he worked on for several years. It was a pleasure to jave Karl on the team.
