I’m ready to launch a multi-vendor ecommerce platform that can comfortably host 50,000+ sellers and deliver a shopping experience on par with Daraz. The site must feel instantly responsive for every user, maintain rock-solid stability under heavy traffic, and meet strict security expectations from day one. Scope and core requirements • Catalogs will include both physical and digital products. Vendors should be able to list either type effortlessly from their dashboard, set inventory or file limits, apply coupons, and track sales in real time. • Buyers will check out with Credit/Debit Card, PayPal, or Bank Transfer. Please integrate each gateway so transactions settle smoothly and reporting stays unified in the admin panel. • Mandatory security layers: SSL across the entire platform and optional two-factor authentication for buyers, vendors, and staff. Feel free to propose further hardening (e.g., fraud detection or bot mitigation) if that improves overall resilience without sacrificing speed. Performance goals The finished site must pass core-web-vitals thresholds, handle peak loads comparable to flash-sale events, and deliver sub-second page transitions. I’m open to your preferred stack—whether Laravel + Vue, Django + React, Magento, or a headless approach—as long as it supports horizontal scaling, CDN use, and clean separation between front-end, vendor micro-services, and payment modules. Deliverables 1. Full source code with documented setup scripts 2. Responsive UI that mirrors Daraz’s ease of use 3. Vendor, buyer, and admin portals with role-based access 4. Integrated payment gateways and sandbox test logs 5. Deployed instance (cloud of your choice) plus hand-off session If you have proven experience building high-traffic marketplaces, let’s discuss your proposed architecture, timeline, and any recommended milestones.
