The stack is the keyword set
Tech ATS screens are blunt instruments: languages, frameworks, platforms, and methodologies, matched literally. If the posting says Kubernetes and your resume says 'container orchestration,' you just lost a point. We mirror the exact terms — and include both acronyms and full forms, because recruiters search both.
But a skills list alone reads like a tutorial invoice. The bullets have to prove the stack: what you built with it, at what scale, with what result.
