LinkedIn is the world's largest professional network and the default place recruiters go to verify a candidate exists. You need a LinkedIn profile. That's not the question.
The question is whether LinkedIn's skill signals are actually useful in a developer job search — and whether a Skeelzy verified resume adds something LinkedIn can't provide. The answer to both is yes.
The problem with LinkedIn skill endorsements
LinkedIn endorsements work like this: your connections click a button to say you know a skill. No test. No demonstration. Anyone who's connected to you and willing to click can endorse you for anything. The result is that most LinkedIn skill sections are meaningless — developers with 99 React endorsements who've never shipped a React component, and developers with 2 endorsements who build React applications every day.
Recruiters know endorsements are unreliable. They use LinkedIn to verify your work history and find you — not to evaluate your skill level.
LinkedIn Skills Assessment: closer, but still limited
LinkedIn does have a Skills Assessment feature — short multiple-choice tests that give you a verified badge if you score in the top 30%. This is closer to what Skeelzy does, and it's genuinely useful.
The limitations: the assessments are broad (not developer-stack-specific), the badge only shows on LinkedIn (not portable to your resume or other platforms), and the test questions are static and widely shared online — so the "top 30%" threshold is easier to game than a fresh adaptive quiz.
Skeelzy's quizzes are developer-specific (React, TypeScript, Node.js, AWS, etc.), the scores appear on your public resume URL and PDF export, and the adaptive difficulty means the score reflects your actual level rather than your ability to find the answer key.
How Skeelzy and LinkedIn work together
These aren't competing choices. You need both — they serve different purposes.
LinkedIn is your professional network presence: work history, connections, recruiter discoverability, and the basic legitimacy signal of existing on the platform. Keep it updated.
Your Skeelzy public resume is your verified skill profile: quiz scores, GitHub projects, and a shareable URL you control. Link it from your LinkedIn profile's "Featured" section. When a recruiter clicks through from LinkedIn and sees verified quiz scores, you've added a layer of credibility that LinkedIn can't provide itself.
The combination — LinkedIn for discovery, Skeelzy for verification — covers both the "does this person exist" and "can this person actually code" questions that every technical recruiter is trying to answer.
