this isn't a comments section for an article, it's a reverse job posting by a human. you appear to be taking pot shots at the commenter with a stated goal of exposing their lack of depth in one of the technologies they listed in their posting. you don't appear to be making a good faith attempt to hire or interview this person. in the context of a "Who is hiring" post, this is antisocial behavior and rude. additionally, nowhere in the post was any sort of claim made that the author is an expert in anything.
