Someone who insults your tech stack. Oh no sorry that's a technology insultant.

It's in the name...they consult on technology.

If someone told me that was their title, I would assume that they were an IT (probably non-developer/engineer) generalist.

Sets up networks, configures hardware, handles purchase orders, etc. Whatever general "tech" things a company might need done that requires a knowledgeable person, but not a specialist.

Another name for freelancer. I code and also have experience in managing IT teams. I decided to go solo and attempted to promote my experience via LinkedIn posts instead of GitHub code commits, for example.
