A versifier is someone who writes verse, especially when the word suggests technical skill without much originality, feeling, or poetic power. It can simply mean "poet," but it is often used with a critical edge to imply that the writer produces rhyme and meter more mechanically than artistically.
Example
The critic called him a mere versifier, saying his lines rhymed neatly but never seemed to say anything fresh.
