I saved my company $50,000/year. A previous consultant (that they were still paying monthly) had written an application that was the backbone of the entire ordering system. If it went down, no work could be done and they needed to call this guy and pay him $150/hour. It was a .net app that I reverse-engineered that was basically calling 10 or so encrypted stored procedures in SQL server. Because the older versions of SQL don't actually use encryption, but a type of encoding, I was able to decode them all and replace the entire app with a script that I wrote. The whole process with testing took about a month (they thought it would take me a year). The consultant that made it wasn't very happy when he was told they would no longer be needing his services.
