I am building a full-scale online store centred on electronics and I want the overall shopping experience to feel as seamless and trusted as Amazon. The site must handle thousands of SKUs, offer fast product search with filters, and adapt smoothly to mobile and desktop screens. Key functions I expect from day one: • Robust catalogue management for electronics (brands, specs, warranty fields, bulk import/export). • Secure customer accounts with order history, wish-lists, and product reviews. • Cart, one-page checkout, and real-time stock updates. • Integrated payments: PayPal, Stripe, direct Credit/Debit Card processing, PhonePe, Google Pay, Paytm, plus Cash On Delivery logic at checkout. • Shipping module that lets me define multiple carriers and live rate rules. • Admin dashboard for promotions, coupons, returns, and analytics (sales, traffic, conversion). • SEO-friendly URLs and schema, along with basic speed optimisation so pages load quickly even under heavy traffic. Tech stack is flexible; I am comfortable with popular frameworks such as Magento, Shopify (headless), WooCommerce, or a custom Node/Laravel build, provided you can demonstrate scalability and PCI-compliant coding practices. Acceptance criteria: 1. Working production site deployed on my hosting with an SSL certificate and test products loaded. 2. All listed payment methods process sandbox and live transactions successfully. 3. Thorough hand-off: source code in my repo, documentation for setup and future feature additions, plus a short walk-through call. If you have launched similar multi-vendor or high-traffic stores, please share links and briefly outline the tech stack you used.
