Northwind Financial
A digital banking platform rebuilt to survive its own growth
Northwind was adding 30,000 customers a month onto a monolith that could only be released during a Sunday maintenance window. We split the core into domain services, moved delivery onto Kubernetes with Argo CD, and stayed on to run it for the first eighteen months.
The maintenance window is gone. Deployments now happen during business hours, and the platform absorbed a 4x traffic peak on results day without a manual intervention.
