E-Commerce Site & Payment Gateway

I need an end-to-end e-commerce website built from scratch, complete with a secure payment gateway. The store should let customers create personal accounts so they can manage orders, track shipping, and store their preferred payment details for future purchases.

At checkout, the platform must process both Credit/Debit Card transactions and UPI seamlessly. If you typically work with gateways such as Razorpay, PayU, Stripe, or similar APIs, feel free to leverage whichever solution best meets PCI-DSS compliance and supports UPI alongside card payments.

Core expectations: • Modern, responsive storefront with product catalog, search, cart, and order history • Account registration,, password reset, and profile management • Integrated payment flow for Credit/Debit Cards and UPI, tested in sandbox and live modes • Admin dashboard to add/edit products, view orders, and issue refunds • Basic security hardening—SSL, CSRF protection, and secure password hashing

Once everything is functional in staging, I will verify user registration, add items to the cart, and complete transactions with both payment types. When those tests pass without errors and the admin tools work as described, the project is complete.
