Can I vibe code Pattern?

Build a multi-channel ecommerce inventory and order synchronization system in Node.js, TypeScript, and PostgreSQL.

1. DATA MODEL:
- Create tables: Products (id, sku, title, cost_price), ChannelListings (id, product_id, channel_name, external_id, channel_price, min_price, max_price), Inventory (product_id, warehouse_id, quantity_on_hand, reserved_quantity), Orders (id, channel_name, external_order_id, status, total_amount, currency, payload).

2. INTEGRATIONS & SYNC ENGINE:
- Build an adapter pattern for Amazon Selling Partner API (SP-API) and Walmart API.
- Implement cron tasks to fetch orders every 15 minutes. Normalize external orders into the internal Orders table.
- Deduct reserved_quantity from Inventory upon receiving an order.
- Implement an outbound inventory push worker that broadcasts updated stock levels to Amazon and Walmart whenever inventory changes in PostgreSQL, using rate-limited queueing (BullMQ + Redis).

3. REPRICING ENGINE:
- Implement a rule-based repricer process running every hour.
- Fetch buy box/competitor price from Amazon SP-API Subscription API / Product Pricing API.
- Calculate target price = competitor_price - 0.01 USD, ensuring target_price >= product.cost_price * 1.30 (30% floor margin) and target_price >= listing.min_price.
- Push updated price to the channel API if target price differs from channel_price.

4. FAILURE HANDLING & IDEMPOTENCY:
- Idempotent webhooks and API polling using external_order_id unique constraints.
- Circuit breakers and exponential backoff retry policies for marketplace rate limits (e.g. Amazon 429 errors).

5. OUT OF SCOPE:
- Do not build physical fulfillment workflows, shipping label generation, or legal IP enforcement functions.
