Can I vibe code Relo?

Build a Node.js and PostgreSQL backend microservice to replicate Relo's predictive replenishment core logic for Shopify stores. 1. Data Ingestion: Connect via Shopify GraphQL API. Sync historical orders and line items. Extract customer ID, variant ID, quantity, created timestamp, and fulfillment status. 2. Predictive Calculation: Group orders by customer ID and variant ID. Calculate the median days between consecutive orders for each SKU. Exclude single-time purchasers from interval math. Define 'Predicted Reorder Date' = (Last Order Date + Median SKU Interval). 3. Cron Scheduler: Run a daily job checking for customers whose 'Predicted Reorder Date' is within 7 days. 4. Integration: Trigger custom events to Klaviyo using the Klaviyo Track API ('Ready For Replenishment'). Payload must include customer email, recommended variant ID, item quantity, and a generated permalink: `https://store.myshopify.com/cart/{variant_id}:{quantity}?discount=REORDER10`. 5. Subscription Upgrades: Include optional Shopify Selling Plan ID parameters in the permalink payload to allow one-click subscription conversion. Handle rate limiting using p-queue. Out of scope: Custom dashboard UI, SMS carrier endpoints.
