webpromahdi/ai-career-saas — reverse-engineered prompt

Build me an AI career SaaS app that helps job seekers improve their chances of getting hired. I want users to sign in with Google, land on a clean dashboard, and use AI tools to generate a stronger resume, prepare for interviews based on a job role, and check how well their resume matches a job description with an ATS style score and suggestions.

Use the stack from this project, React with TypeScript, Vite, and Tailwind for the frontend, plus Node, Express, MongoDB, and JWT auth for the backend. Connect the AI features through OpenRouter using DeepSeek. Keep the app responsive so it works well on phone and desktop, and make sure protected pages only work after login.

Please set up the frontend and backend, the main pages, API routes, environment variable examples, and basic error and loading states. Look up current docs online if you need to.
