The assignment
Build a tool that takes a job description and customises your resume to match. Outputs a finished PDF — not a chat-bound Gem.

ResumeFit is a no-login tool that scores a resume against a job description across weighted dimensions — keyword coverage, role fit, requirements alignment, and evidence strength — and flags gaps it won't fill with invented experience. It generates a downloadable tailored PDF resume and includes an application tracker for managing multiple job-search runs.
Teena shipped a deployed web app you can open. Parts of it sit behind a sign-in, so this read leans on what is public plus Teena's own description.
What it demonstrates
Take this awayThe quiet skill on display is scoping to an artifact. 'Produces a file a recruiter opens' is a spec; 'helps with resumes' is a wish.
The output format is the product. A resume that only lives in a chat window can't be sent to a recruiter — forcing a real PDF is what turns a nice answer into a tool someone would actually use.
A finished file, not a chat answer
Something you could attach to an application: a formatted, downloadable PDF. The brief ruled out anything that only ever prints text into a chat window.
Matching that has actually read the JD
Responding to that specific posting's language and priorities and reordering real experience — as opposed to sprinkling its keywords into the same resume.
It survives the second job description
A pipeline you can run again on Monday, not one artful manual edit dressed up as a tool.
No numeric scores are published here. These pages are written reads of what each builder shipped — the build is the point, not a mark out of a hundred.
