Finalize QR Rewards Web App

I have a mobile-friendly rewards web app that lets users scan a QR code, answer a short survey and instantly unlock promotional offers. The core flow is in place, but the front-end integration still needs attention. Everything is written in plain HTML with light client-side scripting, and at the moment UI/UX inconsistencies are the main hurdle.

Here is what I’d like you to tackle first:

• Review the existing codebase, spot integration gaps between the HTML front-end and the back-end services.
• Smooth out the UI so every screen renders consistently on modern mobile browsers.
• Verify the reward logic, database calls and external API hooks so the right offer is delivered every time.
• Prepare a clean deployment pipeline so I can roll out a production build ahead of my November 1 launch.

Once the app is live, I’ll need periodic help for new features and quick troubleshooting, so ongoing availability is important.

I can share the current repository and build notes as soon as you’re ready to assess the scope.
