E-Commerce Wte with Payment Gateway

I need a clean, fully-functioning e-commerce site built from scratch, with special attention given to smooth, secure payment-gateway integration. The core of the job is to craft a modern storefront where products can be displayed clearly, checkout flows quickly, and customers feel confident entering their card details.

My priorities are:
• A responsive design that looks great on desktop and mobile.
• Direct, seamless connection to a mainstream payment processor (Stripe, PayPal, or a comparable solution—happy to discuss the best fit).
• Backend code that is easy for me to update later—whether we go with Shopify, WooCommerce, or a custom stack, I want straightforward product and order management.

I’m less concerned with advanced features like user reviews or elaborate loyalty programs at this stage; the site simply has to accept payments reliably and showcase products without friction. If you have a proven track record launching e-commerce sites and can demonstrate successful payment integrations, let’s talk.
