Honestly the feeling hasn't completely gone away but I've slowly stopped thinking of myself this way as intensely as I did before. What it took was strong mentorship from a really good boss and exposure to all levels of the stack and strong architectural and technical principles to building robust applications. Taking some interviews I felt much better about myself than I had in years cause I was actually able to answer things that I couldn't have a couple of years ago

I hope you find that place in your life too. It's a lot of relief when it happens
