I want to launch one web platform that lets me both run a full-featured online store and host classified ads in a clean, modern interface. Online store scope • Core catalog will begin with appliances, toys and cosmetics, but the structure must let me add more product lines later. • Shoppers need a familiar flow—search, category filtering, product pages with rich media, cart, multiple payment gateways, order tracking and email/SMS notifications. Classified ads scope • Registered users must be able to post, edit and renew listings for vehicles and housing. • Built-in moderation tools, listing expiry dates and optional paid-promotion upsells are required. Back-office & admin The same admin panel should manage products, inventory, orders, user accounts, ad approvals, reports and role-based access. Please build it with security best practices (OWASP top-10, SSL, encrypted passwords, CAPTCHA, audit logs). Deliverables • Responsive website (desktop + mobile) fully tested and deployed to a staging URL • Source code repository with clear commit history and comments • Database schema and seed data • Deployment script or step-by-step hosting guide (Linux or cloud) • Comprehensive user & admin manuals, plus a simple maintenance checklist (backups, updates, log rotation) Acceptance criteria – Page load under 3 s on 4G for public pages – No high-severity vulnerabilities on an automated security scan – All primary user flows (buying a product, posting an ad, approving an ad) demonstrated live on the staging site. Tech stack is flexible—Laravel, MERN, Django, WooCommerce or another framework you’re comfortable scaling—but please outline your choice and why when you bid. I’m ready to move quickly once I see a solid plan and timeline.
