I'm looking for a synonym for "working on" in this sentence. I feel like there has to be a more concise way than to say "Joe has contributed a lot while working on Project X, Y and Z". Joe has worked on many projects and I am trying to highlight a few specific ones he did very well on.
One phrasing I might use is "while participating in Project X", especially if it were a public/semi-public/open-source project. Other options include "as a part of Project X" and "as a member of Project X".
Well, if you're looking for a more concise way, how about simply saying:
Joe has contributed a lot to Project X, Y and Z.
