I took a few core CS classes throughout university in the late 90s/early 2000s - database design (Oracle), general programming (C++, Java), unix (Solaris) that were foundational. But for the most part, I focused on building domain expertise. Writing software was just another tool in my toolkit. Most of what I discovered was through pragmatic application, just-in-time learning. 20 years later and all I do is write software. If I could start over, I'd spend a few years on the fundamentals. Learning programming for the sake of programming. Understand how computers actually work, detached from my work goals.
