Ecommerce Site With Advanced Filtering

I need a full-featured online store for physical products, built from the ground up with an emphasis on a lightning-fast product filtering and search experience. Shoppers must be able to drill down by category, price, specs, or tags in real time without page reloads, so please factor in elasticsearch-style indexing or an equally responsive solution.

Must be built in Wordpress

Credit and debit card payments, as well as PayPal, have to be integrated at checkout with clear, PCI-compliant handling. A clean, mobile-first design is essential, and I’m open to frameworks such as Shopify, WooCommerce, Magento, or a custom React/Node stack—whichever you can leverage to hit top page-speed scores.

Core deliverables:
• Fully responsive storefront with advanced filtering/search
• Secure checkout accepting credit/debit cards and PayPal
• Dashboard for easy product, order, and customer management
• Basic on-page SEO setup and launch support

Hand-off isn’t complete until the site is live on my domain and I have admin access, clear deployment notes, and a quick walkthrough video.
