I want a clean, fast e-commerce site that lets visitors browse my products and check out in one seamless flow. The core requirement is a fully working payment-gateway integration so orders can be processed the moment the store goes live. Here’s how I picture the job: • Build the site on a stable platform you’re comfortable scaling. • Design must stay minimal and mobile-friendly; shoppers should reach the cart in as few clicks as possible. • Configure, test, and secure the payment gateway of choice so transactions clear without manual intervention. If you can also weave in best-practice SEO structure and leave room for future add-ons like product search or customer reviews, great—just make sure checkout works flawlessly first. Deliver the launch-ready site along with any admin credentials and a short hand-off guide so I can manage inventory on my own after release.
