My first full time paid developer job was to be a Developer on the Spooler/Spooler Plus components which were part of the HP Tandem NSK.

I had a really good mentor when working on this product and I learn the importance of modularity in design. I was just off my internship doing a D2K/Oracle implementation for an airline in-cabin inventory application, so working on Spooler was a breath of fresh air.
