Worked 5 years as a contractor for a system made to be used for all of the healthcare in a country. Payed by tax payer money. Some serious money. I never understood what the system actually was supposed to do during those 5 years. Started as some custom authorization server for new healthcare laws and then ended up as some kind of desktop app that had a launcher to launch apps. No idea what the purpose really was and heard it got cancelled a couple of years after i left.
