I need a complete online shopping site modelled on the user experience of giants like Myntra and Flipkart. The core idea is to host a wide catalogue, display products in category-driven pages, and guide customers smoothly from discovery to checkout. Key areas I want handled include: • Robust product database with search and filter tools that stay fast even at scale. • Secure account creation and sign-in that remembers user preferences and past orders. • A seamless cart-to-payment flow supporting major gateways as well as cash-on-delivery options. • Mobile-first responsive design so the store feels native on phones and tablets. • An intuitive admin dashboard where I can add or edit listings, manage stock, view sales analytics, and run promotions without touching code. Though my inspiration is from large multi-category portals, the initial launch can start with a few product lines and grow—so please propose a scalable architecture. If you have pre-built modules or can leverage frameworks such as Magento, Shopify Plus, WooCommerce with custom React/Next.js front-ends, or a full MERN stack, let me know which route you recommend and why. I’m looking for a clean, modern interface, quick load times, and code that’s easy to maintain. Share live links to comparable stores you have built, outline your timeline with major milestones, and specify what post-launch support you include.
