Can you say "computer savvy"?

[Sneymarin]

Hello, I would like to know if "computer savvy" is used correctly in this sentence: "I'm not a computer savvy". Someone suggested that it's "I'm not computer savvy" instead. If it's not correct, could you also explain why?
Thank you for your time.

"Savvy" is a an adjective, not a noun, so you cannot have an article before it. I would hyphenate "computer-savvy".
