accidental techie 

The accidental techie is usually a person who understands computers or office equipment better than most in the organization, and can figure out how to adapt the knowledge to the organization's needs. This is the go-to person for technology issues at an office that doesn't have or can't afford tech support.

After Jason fixed Ellie's screen resolution he quickly became the accidental techie.
