(Hearing a new word at a gathering of writers—who would have though?)
The meaning of factotum is a person having many diverse responsibilities (or activities.)
This could be a general servant, a handyman (or handyperson if you prefer)/repairperson or someone who does all kinds of work around the home or office.
At time, it has meant any employee or official who has many differing responsibilities.
The Latin derivation is fac totum, which means to do or make everything.
