Build me a full stack AI voice interview practice app where a user can set up their profile, upload a resume, and start a realistic mock interview with a live voice interviewer in the browser.

The app should ask smart, role specific questions based on the user’s experience, skills, and resume, avoid repeating questions, and show microphone activity and speaking feedback while the interview is happening. After the session, I want a clear report with scores for things like technical ability, communication, confidence, problem solving, clarity, and overall performance, plus helpful strengths, weaknesses, and study tips.

It should also save interview history, let me review past sessions, and include a simple settings area where I can enter the needed Vapi credentials and assistant ID. If you need to look up current docs online for Vapi or Gemini, go ahead. Make it feel polished and production ready, with a clean modern UI and working backend endpoints for starting interviews, uploading resumes, saving transcripts, and ending sessions.
