Cobalt
Single column · Cobalt-blue accents · Icon contacts · ATS-safe
A crisp, single-column resume with a bold navy name, uppercase section headings underlined by thick rules, and vivid cobalt-blue degree/role and skill labels.
Icon-led contacts, a right-aligned GPA block, and dashed entry separators keep it clean and ATS-friendly — ideal for computer-science students, new-grad engineers, and internship applicants. Named for the cobalt-blue accents that define the design.
