Build a multi-channel inventory synchronization and order management backend service in Node.js (TypeScript) using PostgreSQL and Redis BullMQ.

1. DATA MODEL
Create Postgres schemas for:
- MasterSKUs (id, sku, barcode, title, cost_price, base_price, weight)
- Warehouses (id, name, location_code)
- InventoryLevels (master_sku_id, warehouse_id, quantity_on_hand, quantity_reserved, safety_stock)
- SalesChannels (id, platform_type ['shopify', 'amazon', 'custom'], credentials_json, status)
- ChannelListings (id, sales_channel_id, master_sku_id, external_product_id, external_sku, price)
- Orders (id, sales_channel_id, external_order_id, status ['pending', 'allocated', 'fulfilled', 'cancelled'], total_amount, shipping_address_json)
- OrderItems (id, order_id, master_sku_id, quantity, unit_price)
- SyncLogs (id, sales_channel_id, action, status ['success', 'failed'], payload_json, error_message)

2. CORE FUNCTIONALITY
- Webhook Ingestion: Build endpoints to receive incoming order webhooks from Shopify and Amazon.
- Order Allocation Engine: When an order comes in, place an immediate row-level lock on InventoryLevels. Reserve stock across assigned warehouses based on priority logic. If total quantity_on_hand minus quantity_reserved is less than ordered quantity, mark order as 'backordered' and emit an alert log.
- Inventory Synchronization: Create a background queue job triggered on any inventory change. For every connected SalesChannel, calculate available stock (quantity_on_hand - quantity_reserved - safety_stock) and dispatch an API update call to the respective channel.
- Central Dashboard API: Build endpoints to fetch real-time aggregated inventory levels, order statuses, and recent SyncLogs with failure filters.

3. RESILIENCE & FAILURE HANDLING
- Exponential Backoff Queue: Use BullMQ for channel API requests. Handle rate limiting (e.g., HTTP 429) gracefully using exponential backoff up to 5 attempts.
- Idempotency: Store incoming webhook IDs in Redis with a 24-hour TTL to prevent double-allocation of duplicate webhook deliveries.
- Conflict Resolution: If an inventory push fails, log the full response payload in SyncLogs and schedule a retry job.

4. OUT OF SCOPE
- Full WMS mobile scanner hardware integrations.
- EDI 850/856 parsing.
- Automatic repricing engine.
