Just keep in mind that a lot of the time even if you start off right, new management comes in, thinks that consultants are for "busy work", tries to relegate you to that, then has you putting out little fires they create. And if you are clearly doing better work compared to what the new CTO is capable of? Well, it goes two ways - you are valued and praised or you are pushed out because you are perceived as a threat to their authority. And guess which way it goes a lot of the time when a CTO asks you for a "deploy document, showing which file will be moved, by whom, to which machine, and who will send out a notification email" and you tell them it's all automated in a yaml file and you just push a button.
