Write an About Me section

I need a brief, professional ‘about section’ for LinkedIn. Something to the effect: I started in residential roofing and exterior (selling and project managing job). Transitioned into estimating roofing, exteriors, and sheet metal. And now project manage commercial roofing, metals, and waterproofing on public and private facilities ranging from schools, military bases, and high rise buildings.

I attached photos of bullet points on old resumes. Not too long About section. Just professional.
