But maybe this isn't really what they felt that they needed at the time? I don't mean to defend bad practices, but your comment makes it sound like nobody had tasked you with re-architecting the business, and you took it upon yourself to show them how it should be done (in your opinion), without having earned the necessary trust. This might have also come across as patronizing, or at least antagonistic, and in any case unbeneficial. Not saying that's the case as I obviously wasn't there, just something to think about.
Fair comment. And I'm usually suspicious of young engineers wanting to implement the new hotness and I'm also a fan of "if it ain't broken don't fix it". In this case, though, the system was in very rough shape. Our customers were complaining about data problems which we had no way to fix (short of manually editing the prod db, which was the SOP). I definitely took it upon myself to do something that nobody had asked for, but it was because the people in charge were entirely asleep at the wheel! They did not last long in their positions.
