rt2364/resume_analyzer ? reverse-engineered prompt

Build me a full stack resume analyzer web app where someone can upload a PDF resume and paste in a target job description, then get an AI review with an ATS score, match percentage, strengths, improvement tips, and the missing keywords they should add.

I want users to be able to sign up, log in, and stay authenticated securely. Each analysis should be saved to their account so they can open a history panel and see past scans later. The main screen should feel like a modern dashboard with a dark mode look, clear score cards, keyword badges, and an easy way to upload a resume and run a new analysis.

Use a React frontend and a Node and Express backend with MongoDB for storing users and scan history. Handle PDF parsing on the server, send the extracted text plus the job description to Google Gemini, and return a clean structured result to the UI. If you need to check current docs for Gemini or any library details, look them up online first.
