The Challenge

_

Allica Bank needed to integrate a recently acquired lending platform into its main banking system while simultaneously accelerating delivery of new current account features. The migration posed significant risks: moving thousands of loan records without disrupting service, maintaining regulatory and data integrity, and doing so at speed.

At the same time, Allica wanted to shift toward a modern DevOps culture to support rapid product innovation, something its existing processes weren’t fully equipped for.
