I've heard similar complaints before. And, I get it, too-- at a glance, that person is playing the "superhero" by saving the project. But, good management will insist on root causing failures where this will unravel. If it's a recurring problem, you should bring it up with management.
Developers complain about management but tend to forget that managers are people just like everyone else, and we need to apply some skill to our interactions if we are to get the results we desire.
Do you have any resources you've found helpful improving your skill at this?
You can have management that understand tech who will get to the bottom of the problem and you can have management who don't understand tech. They won't.
Management who don't understand tech will either keep somebody on hand who they know and trust who does understand tech (e.g. a consultant) or, more likely, they'll just keep rewarding the faux superheroes who keep screwing up and bailing themselves out.
