Cross-border E-commerce Order Hub
Aggregates orders from multiple marketplaces into one fulfilment pipeline.
Background
The client sold on Amazon, Shopee, and their own storefront, and operations staff were switching between three back-ends all day. The hub pulls orders into a single view, matches them to warehouses and carriers automatically, and writes inventory changes back to each marketplace in real time to prevent overselling.
Tech stack
- React
- NestJS
- PostgreSQL
- Redis
- RabbitMQ
Highlights
- Single unified order view — operations staff no longer switch between back-ends
- Inventory write-back within 3 seconds; overselling complaints down roughly 90%
- Refund tickets route automatically; finance reconciliation cut from 5 days to 1
