Problem

Factory orders, payments and deliveries lived on paper — nobody knew exactly who ordered what, paid what, or owed what.

Solution

1. 01Four roles — sales, factory, warehouse, auditor — each sees and confirms its own stage.
2. 02QR receipts and delivery documents are generated server-side as PDFs; two-step payments and credit tracking.
3. 03Found and fixed three race conditions (simultaneous stock-in and cancellation) with transactional writes.
4. 04The landing is a scroll-driven 3D story: rose → petals → soap → shampoo.

Outcome

The factory now runs order-to-delivery in one system — paper bookkeeping is gone.
