Fix Critical AWS Website Bugs PLEASE READ

My site is already hosted on AWS, feature-complete on paper, yet five key components refuse to work and our go-live is now less than two weeks away. Every failure is consistent and repeatable, so I’m looking for someone who can dive straight into production-level debugging and close these gaps fast.

The components that must be repaired:
• Email verification (custom-built)
• Dialer system (Twilio)
• Booking system (custom-built)
• Payment system (Stripe)
• Live functionality / real-time chat

All code will stay where it is—nothing leaves AWS—so you’ll need solid AWS console familiarity alongside everyday full-stack skills. I can provide repository access, architecture notes, and direct contact with the previous developer if needed.

Acceptance is simple: each item above must perform reliably under normal user load, pass my own end-to-end test scripts, and remain stable for 48 hours in staging before we flip the live switch. If any hotfixes are required after launch, I expect a prompt turnaround.

Please outline your approach, relevant AWS + Twilio + Stripe experience, and confirm you can commit to the 14-day window.
