Rebuilding commerce infrastructure for peak-season scale

Challenge

Seasonal sales events repeatedly caused checkout failures on infrastructure that couldn't scale fast enough.

Approach

We re-architected the commerce platform around autoscaling compute, a decoupled checkout service, and load-tested every critical path against projected peak traffic.

Implementation

Delivered ahead of the next major sales event, validated with full-scale load testing in a staging environment.

Outcome

The platform handled its highest traffic day on record with no checkout downtime.
