The vast majority of my colleagues would say "that person is a devops" instead of "that person does devops", which I don't get at all. I've assumed it's some deeply rooted misunderstanding of language (my colleagues are eastern european) that has taken hold across the entire local industry.
The wiki for “programmer” has “software developer, a software engineer, a programmer or a coder” as interchangeable terms in the first sentence.
