The service was written by a contractor from a cheaper outsourcing company. Nine years later, I still remember his name. The most memorable part of that code was a single thirty thousand line function. To figure out what it does, I had to print it on paper, lay out the sheets on my desk, and annotate them with a pencil. It turned out that it was the same block of code, repeated fifty times with different conditions. I guess someone was paid by the number of lines of code.
