Build a multi-supplier order routing and inventory sync engine in Node.js (TypeScript) with PostgreSQL and Redis (BullMQ).

1. DATA MODEL:
- Create schemas for: Products, Variants, SalesChannels, Suppliers, SupplierVariants (mapping external supplier SKU to internal variant ID, cost, stock, lead time), Orders, LineItems, and PurchaseOrders.

2. INVENTORY SYNC ENGINE:
- Build an extensible ingestion pipeline supporting FTP/SFTP CSV files and REST API endpoints.
- Create a flexible mapping mechanism that maps custom CSV header names (e.g. 'Qty_Available', 'Item_Number') to normalized internal fields.
- Implement scheduled Cron background jobs via BullMQ to fetch feeds, run mapping logic, and update central inventory levels.
- Push total aggregated inventory quantities to connected Sales Channels (e.g., Shopify GraphQL API) with throttling protection.

3. ORDER ROUTING ENGINE:
- Listen to incoming order webhooks from Sales Channels.
- Evaluate order line items against fulfillment rules: Priority 1: Single supplier with 100% stock; Priority 2: Lowest fulfillment cost; Priority 3: Split order into multiple Purchase Orders.
- Transition order status to 'ROUTED' and create associated Purchase Order records assigned to relevant suppliers.

4. FULFILLMENT DISPATCH & TRACKING:
- Transmit created POs to suppliers via HTTP POST or automatically generated PDF attachments via SMTP.
- Expose an API endpoint for suppliers to post tracking numbers (Carrier, Tracking Code, PO Reference).
- Upon tracking receipt, call Shopify Fulfillment API to mark items as fulfilled and notify end customers.

5. ERROR HANDLING & LOGGING:
- Log all failed file fetches, mapping errors, and API delivery failures to an AuditLog table with detailed stack traces.
- Provide automated alert notifications (Webhook/Slack) on critical mapping exceptions.
