I’m struggling to find the right word for “type of person” … words like “nerds” and “jocks” can be limiting, since plenty of people are both.

The guy who got me into tech and computers was a former green beret. Most athletic guy I’ve ever known, and a genius with tech.

I don’t think he was a nerd, but this is really subjective.
