E-commerce Site with Payment Gateway

I’m setting up a brand-new e-commerce website and need a developer who can take it from concept to launch. The core requirement is a reliable, well-documented payment gateway integration so customers can complete purchases smoothly and securely. The build will start with a clean, responsive front end and an intuitive admin panel where I can add or edit products myself. I’m open to your preferred stack—whether that’s WooCommerce, Shopify custom theme work, or a headless setup—so long as checkout speed, PCI compliance, and straightforward maintenance are achieved. Key deliverables: • Fully functional e-commerce site, mobile-ready • Payment gateway integrated and tested in both sandbox and live modes • Brief documentation or walk-through so I can handle routine updates If you have portfolio pieces that highlight similar work, feel free to point me to them when you bid.
