I am not emitting an ethical judgement on what he does btw, merely suggesting that: If you think that what he is doing can be achieved by an incompetent person, then why don't you simply do it yourself ? Why don't you become the guy that can manage + actually code stuff ? Surely you can set aside 10% of the effort you use when writing your libraries and invest them in overtaking this guy's job/position since an incompetent person can achieve what he does. Sure you might not like what he does, namely managing, but that's a role that will probably be filled in any company you apply to. Maybe take a bite of the bullet and invest 1/10th of your time even if you don't like it to actually render this guy useless, eventually fired or released since he is so "incompetent" ? If this ends up not sounding as "easy" as you thought, maybe take some time to rethink your approach, your philosophy towards the situation... As many here have already said...
