It is not generally a good thing to have a "banner" on a resume/cv, which is supposed to provide facts about training, experience and interests. A statement of this kind could be included in the cover letter.
"He is/I am someone who combines good technical knowledge with a talent for selling"
"He is/I am a sales person with a solid technical background".
