The problem
Every November: a war room, a code freeze from September, and an outage budget measured in millions per minute. Growth had outrun the platform.
What we built
An event-driven commerce core with cell-based isolation — checkout, inventory, and pricing scale independently, and a failure in one cell strands one percent of traffic, not all of it.
