"feeling like a fraud" is pretty common, it is formally called "imposter syndrome". It is usually just your mind playing tricks on you; there is a delta between your internal picture of what a "real" programmer (or senior manager, or whatever position) looks like and your internal image of yourself. One solution is to duck type yourself until the feeling goes away. Another is to start to recognize that some of your internal definitions might not be shared by others. I'll leave it as homework to decide which internal definitions matter the most here.
