Can I vibe code WakeupData?

Build a light feed-management service using Node.js, Express, and PostgreSQL.

1. DATA INGESTION
- Create a system to import product catalogs via Shopify GraphQL Admin API or standard CSV/XML file upload.
- Store product records in a PostgreSQL database with attributes: id, sku, title, description, price, compare_at_price, stock_quantity, image_url, category, vendor, product_type, and extra_metafields (JSONB).

2. RULE ENGINE
- Build a JSON-configurable rule engine that executes sequentially over every product in a catalog.
- Support action types: 'replace_string', 'prepend_text', 'append_text', 'set_value_if_empty', 'calculate_discount_percentage', and 'exclude_product'.
- Implement conditional logic: IF stock_quantity == 0 THEN exclude_product; IF price > 100 THEN prepend 'Free Shipping - ' to title.

3. SCHEDULER & GENERATOR
- Set up node-cron to trigger catalog refreshes and rule execution on a daily schedule.
- Create a feed renderer that exports processed products to Google Shopping XML schema (rss 2.0 with g: namespace tags like g:id, g:title, g:description, g:link, g:image_link, g:availability, g:price).
- Store generated XML files on local storage or S3 bucket, exposed via static HTTP endpoints (e.g., /feeds/google-shopping.xml).

4. ERROR HANDLING & LOGGING
- Log feed generation status, execution duration, total processed SKUs, and excluded SKU count in a feed_runs table.
- Handle missing required fields by skipping problematic SKUs and outputting a validation summary report.

OUT OF SCOPE:
- Dynamic promotional image generation.
- Niche marketplace direct API publishing (focus purely on XML feed URLs).
