Contact first, sections in a fixed order
The five contact fields (name, email, phone, city, link) make the header: the name sits on its own line and any filled contact details follow it, joined with a pipe so a mail client does not have to guess. A filled field is a line; an empty field is simply skipped, and an empty section disappears from the resume entirely rather than leaving an empty heading behind.
After the header come the summary, the experience, the education and the skills - the order a recruiter skims in. Removing every job removes the EXPERIENCE section, not the word EXPERIENCE on its own.
