Can I vibe code ChannelPilot?

Build an internal feed generation and competitor price monitoring system in Node.js, Express, and PostgreSQL with a React admin frontend.

1. DATA MODEL:
- Store Products: id, sku, title, description, price, cost_price, image_url, inventory_qty, raw_attributes (JSONB).
- Export Feeds: id, channel_name (e.g., 'google_shopping', 'facebook_catalog'), format (xml, csv), attribute_mapping (JSONB), generation_schedule (cron), destination_url.
- Competitor Targets: id, product_id, competitor_name, target_url, selector, scrape_frequency.
- Price History: id, target_id, price, currency, fetched_at.

2. FEED ENGINE:
- Worker process that pulls active products from database.
- Apply JSONB attribute transformations based on channel_name map (e.g., append brand to title, strip HTML tags from description).
- Stream results into XML (Google Merchant format) or CSV (Meta format).
- Store output files on S3/Cloudflare R2 and output public access URLs.

3. PRICE SCRAPER ENGINE:
- Scheduled background job using Puppeteer/Playwright with proxy rotation integration.
- Scrape target_url for price selectors. Handle basic currency extraction and decimal parsing.
- Alert team via Slack webhook if target SKU drops price by >10%.
- Prevent scrape loops: enforce rate limits per competitor domain.

4. ADMIN UI:
- Attribute mapper page: interface to map store schema attributes to standard Google Shopping tags (gtin, brand, mpn, google_product_category).
- Price monitoring dashboard showing historical line charts of store price vs competitor price per SKU.

OUT OF SCOPE:
- Direct write-back marketplace order sync (Otto, Zalando API integrations).
- Complex automated bidding rules for Google Ads.
