    I’m preparing to launch an online store and need a skilled web developer to create the entire e-commerce site. The must-have for this first phase is a fully functional shopping cart that lets customers add, remove, and edit items seamlessly across desktop and mobile.

If you have experience adding payment gateways or product-review modules, that flexibility will be a plus for later milestones, but the initial focus is getting the store live with the core cart experience rock-solid. I’m open to the framework or platform you’re most comfortable with—whether that’s Shopify, WooComm...
