Would you mind sharing what kind of software you write? This is interesting to me, since I'm self-taught and seem to have done well in my career so far (4 years in), but now I'm going through core CS books and courses, worried that I'll hit a ceiling and wanting to fill the gaps in my knowledge. I work in devops and infrastructure.
