Omnichannel Multi-Store Inventory & Order Bridge
A high-reliability inventory bridge built to solve overselling across multi-channel retail operations. Ingests order webhooks from Shopify, WooCommerce, and physical POS systems, computes centralized inventory delta transactions, and pushes updated stock counts back in sub-seconds.
Business & Technical Friction
- Retailer selling identical inventory on both Shopify and WooCommerce suffered frequent overselling during flash sales.
- Manual end-of-day stock reconciliation took 2 hours daily and was prone to human counting error.
- API rate-limits on store platforms caused synchronization backlogs.
Architecture & Implementation
Constructed a central event bus using Redis and BullMQ queues. When an order is placed on any channel, the bridge locks inventory, updates the master PostgreSQL database, and broadcasts updates to remaining channels instantly.
