Case 1
The resume says: "Created responsive websites using HTML, CSS, and JavaScript."
The roast: You used the three technologies that have defined the web since before some of your reviewers were born. This is not a skill, it is literacy. What did the websites do, for whom, and what changed?
Why it is weak: HTML, CSS, and JavaScript are baseline literacy for frontend roles. Listing them as an achievement invites the reviewer to keep looking for one.
Improved: Rebuilt a marketing site in Next.js with responsive breakpoints and image optimization, raising Lighthouse performance 58 to 97 and mobile conversion 14%.
Why it works: Same foundation, but now there is a framework choice, a performance result, and a business metric. The technologies become context instead of the entire claim.
