I want to launch a responsive online store dedicated to pet lovers, selling three main lines—pet food, toys, and accessories. The overall look should be modern and clean, with smooth navigation that lets visitors find exactly what they need in as few clicks as possible. The heart of the build is an intuitive product search and filtering system. Shoppers must be able to narrow items by category, size, brand, price range, and other relevant attributes without a page reload. Speed and clarity here will make or break the experience, so please give this feature extra attention. I’m flexible on platform (Shopify, WooCommerce, Magento, or a custom stack—whichever you know best). Whichever route we take, the store must be mobile-first, SEO friendly, and ready for secure payment processing from day one. Deliverables • Fully designed, modern storefront tailored to pet food, toys, and accessories • Advanced AJAX-powered search and filter functionality • Product pages with high-quality image galleries and clear variant handling • Secure checkout integrated with at least one major payment gateway • Admin dashboard for easy product, order, and inventory management • Basic on-page SEO setup and performance optimization Acceptance criteria 1. Filtering returns results in under two seconds on desktop and mobile. 2. All core pages score 90+ on Google PageSpeed Insights mobile test. 3. Checkout passes a live test transaction without errors. If you have past examples of similar ecommerce builds, especially in the pet niche, please share links so I can see your approach to design and usability.
