article reviewing or article reviews [duplicate]
Both are grammatically correct. do is a transitive verb, and the receiving noun in the first sentence is "article reviews" while the receiving noun in the second sentence is "article reviewing".
The first sounds more natural, and it implies some fix quantity. For example, you can do 5 reviews, 10 reviews, 100 reviews, etc.
The second feels like it's more of a general job versus a quantifiable metric as in the previous sentence.
