Project description:
"Project: Master - Child E-commerce (Dropshipping) Objective: Build a system with one Master site (supplier) and multiple Child sites (resellers). The Master manages catalog, nightly CSV import, price rules (public/reseller), shipping, KMoney payments, orders, and customers. Child sites sync products from the Master (only allowed categories), generate orders, but payments and fulfillment are processed by the Master. Profit reports: the Master sees revenue and margins per reseller (Public − Reseller), each Child sees only its own profits. Master features: Product catalog with SKU, descriptions, images, categories, attributes, brand, purchase price, public price, reseller price, stock. Nightly CSV import with product creation/update, stock, prices, images, and logs. Multi-level price rules (global, category, brand, SKU) with priorities and rounding. Shipping costs by category/weight/zone. KMoney payment integration. Receive orders from Child, reserve stock, manage shipping and tracking. Vendor panel: allowed categories, orders, revenue, margins, CSV export. Child features: Catalog synced in read-only mode, limited to categories enabled by Master. Checkout creates order on Master; status and tracking synced back. Profit dashboard with calculation (Public − Reseller), CSV export. Master Child integration: Authentication per reseller, security (timestamp, idempotency, rate limiting, IP allowlist). Required endpoints: products, stock, prices, orders, webhooks for updates. Performance: handle 10k+ products, fast stock/price sync. Developer requirements: Proposal must include the chosen technology stack, reasoning, at least one alternative with pros/cons, architecture diagram, work plan/tests, security approach, expected performance, documentation, and timeline with costs."
