I need a full-stack developer to build a production-ready e-commerce web application. The core requirement is a seamless, secure payment-gateway integration, so experience with APIs such as Stripe, PayPal, or similar services is essential. Everything from front-end customer flows to back-end order processing should work smoothly around that gateway. The initial release must allow visitors to browse products and complete a purchase without friction. If you can structure the code so features like a shopping cart or product-review modules can be added later, that forward-thinking will be appreciated. Deliverables • Responsive web application deployed on my hosting account • Fully tested payment gateway integrated and live-transaction ready • Clear setup & deployment documentation so I can reproduce the build locally or on another server Please outline your preferred tech stack, previous payment-gateway projects, and an estimated timeline to get the first version online.
