What is my job title ?

Hello,

I was once hired by a homeowner to assist his home construction crew to ensure a timely completion of the build (the GC became quite ill at the end of the job). Things I would do include return / replace items by mail, order parts, track worker hours and cut their checks weekly, coordinate deliveries, communicate with the town hall as needed, support the crew. I have no construction experience, I was just doing stuff so that the crew could concentrate on the job at hand.

I’ve recently been contacted by someone who suggested I work doing similar for a major construction firm who is looking for someone to join their team in this type of role.

What would this be called? Project coordinator? Something else?
