Website & Mobile App with Payments

I need a complete digital presence that includes both a modern, responsive website and a companion mobile app for iOS and Android. The heart of the project is a smooth online-payment and booking flow, so the entire user journey—from browsing to checkout—must be seamless, secure, and fast.

Here is what I expect to receive:
• A polished website built with a contemporary front-end framework and a scalable back-end API.
• A mobile app (native or cross-platform) that mirrors the website’s functionality and design language.
• Full integration of a reliable payment gateway (Stripe, PayPal, or a comparable solution) with real-time booking confirmation.
• An admin panel where I can manage inventory, view transactions, and issue refunds when necessary.
• Source code, deployment guides, and brief walkthrough video so I can maintain and extend the platform after launch.

If you have a track record of shipping secure payment systems and can keep both the website and app visually aligned, I’d love to see your proposal and timeline.
