Key point
One rule
Your skills and experience should point to one target role. If you want frontend roles, React, JavaScript, CSS, Git, and API integration belong above random tools you tried once.
Only list what you can explain in an interview or prove with a project, repo, certificate, or role.
Skills are signals
LinkedIn skills are not a trophy shelf. They help a recruiter or builder quickly understand what you can do.
Choose 10 to 15 strong skills first. Put your best 3 to 5 near the top. These should match your profile goal from lesson 1 and your projects from lesson 4.
