Can I vibe code Syncee?

Build a multi-supplier inventory synchronization and catalog mapping system using Node.js, TypeScript, PostgreSQL, and Prisma. 

1. DATA MODEL:
- Supplier: id, name, feed_url, feed_format (CSV/XML/JSON), sync_frequency_minutes, auth_credentials.
- FieldMapping: supplier_id, source_field, target_field (sku, title, price, quantity, images, variant_attributes).
- Product: id, supplier_id, vendor_sku, title, wholesale_price, retail_price, stock_quantity, shopify_product_id, shopify_variant_id.
- MarkupRule: id, supplier_id, category, multiplier, fixed_fee.

2. CORE FUNCTIONALITY:
- Feed Fetcher: Cron job using BullMQ that fetches remote inventory files via HTTPS or FTP based on sync_frequency_minutes.
- Parser: Parse XML, CSV, or JSON payloads into unified Javascript objects based on FieldMapping configuration.
- Pricing Engine: Apply MarkupRule to wholesale_price to compute retail_price (e.g., wholesale * 1.4 + $2.00).
- Platform Synchronizer: Rate-limited worker that uses Shopify GraphQL Admin API (productSet mutation) to create or update products, variants, and stock quantities.
- Order Forwarder: Webhook listener for Shopify order creation. Filter items by supplier_id, construct standardized JSON order payloads, and dispatch them to the corresponding supplier API endpoint or generate an automated Purchase Order email.

3. FAILURE MODES & RESILIENCE:
- Feed Delays: Retries with exponential backoff if remote feed server returns 5xx or times out.
- Schema Drifts: Log validation errors if mapped fields are missing; alert via email/slack without stopping execution for valid records.
- Rate Limits: Enforce a strict token bucket algorithm for Shopify GraphQL API calls (max 40 points/sec).

4. OUT OF SCOPE:
- Do not build a public marketplace UI for vendor browsing.
- Do not handle payment capture or vendor payouts.
