The challenge
Label generation slowed to a crawl during peak season, and every new carrier integration took weeks because logic was scattered across a monolith.
What we built
We introduced a carrier adapter pattern behind a unified rating and labelling API, moved label generation to an event-driven worker pool on EKS with autoscaling, and added end-to-end tracing across every carrier call.
The result
The platform processed four times its previous peak volume with no incidents, new carriers now integrate in days, and infrastructure costs dropped by more than a third.
