WhatsApp OTP E-Commerce Website

I need a custom-built e-commerce website that delivers a fast, friction-free shopping experience. Customers will create an account with their mobile number and confirm it instantly through a WhatsApp OTP, then browse a streamlined catalogue, add items to their cart and check out in just a few taps on any device.

The checkout flow must support Credit/Debit Card, PayPal and Bank Transfer, and a live-chat widget should let me assist shoppers in real time. On the back end, I want a clean admin panel where I can add or edit products, upload images, adjust prices, track stock and review every order that comes in.

Deliverables
• Responsive storefront (mobile-first) with product search, filtering and detailed product pages
• Secure user registration/login with WhatsApp OTP verification
• Cart, checkout and order confirmation screens wired to Credit/Debit Card, PayPal and Bank Transfer gateways
• Admin dashboard for full product and order management
• Integrated live chat support
• Well-structured, documented codebase ready for future scaling and feature additions

Acceptance criteria
• Page load times under two seconds on 4G mobile
• Successful end-to-end purchase flow for all three payment methods in a staging environment
• WhatsApp OTP delivered and validated within ten seconds for 95 % of attempts
• No critical issues flagged by OWASP ZAP or similar security scan

Feel free to suggest the most efficient modern stack—Laravel, Node.js, Django or another equivalent—provided it meets these performance and security benchmarks. Once we agree on the approach, I’ll supply branding assets and product data so you can get started right away.
