Challenges

Peak traffic

Flash sales drive 50x traffic spikes that must not drop a single order.

Inventory accuracy

Overselling across channels erodes trust; inventory had to be correct in real time.

Solutions

Elastic checkout

A queue-buffered, horizontally scalable checkout absorbs spikes without overselling.

Real-time inventory

Event-sourced inventory with reservations keeps every channel perfectly in sync.
