AI Quiz App Fix & Integration

I need help with my AI-powered quiz tool built on Base 44

Key tasks include:
- Regaining access to the back office (currently can't log in or receive emails)
- Making the quiz fullscreen and mobile responsive
- Ensuring email output (results/notifications) works
- Embedding the app cleanly into my main website

Ideal Skills:
- Experience with software and no-code platforms
- Front-end development (HTML/CSS, responsiveness)
- Troubleshooting ability

This is a quick but urgent job. App link available on request. Flexible budget for the right candidate.
