I can speed up most commonly used shopping carts / webshop engines, such as opencart, wordpress+woocommerce, joomla, magento, etc. I need access to the hosting via FTP, I only modify a few files. NOT AVAILABLE FOR SHOPIFY, ETSY, or similar sharecrop-based shops. If your shop was built on the shopify, etsy, or similar "rent-a-shop", or "pay-as-you-go" platform, speeding it up is impossible from the user's or developer's end. If you really want to have a fast platform, I can set it up for you with real hosting, and real shop engines, like Wordpress, Opencart, Prestashop, and similars that were specifically built for e-commerce.
