Synonym for "geek" (computer geek) with positive connotation

Something like "IT expert" or "computer expert" seems verbose. Is there something better? I am looking, though, for a word with that (IT/computer expert) meaning. Something like "mechanic", "actor", "designer"... But something general like "geek" is, as opposed to a more narrow meaning word like "developer".

(Before I'm asked why I think it has negative connotations: See Wikipedia on Geek: "with a general pejorative meaning")

Solution 1:

You could use computer guru, but if you need a single word, I'd suggest techie.

Techie (noun): Someone who knows a lot about computers or other electronic equipment.

[Cambridge English Dictionary]

Lexico also gives computernik and computer jock for a computer expert/enthusiast.
