Core Banking Platform Modernisation
Migrating a 25-year-old core banking system to cloud-native architecture

The Challenge
A regional bank's core system was written in COBOL, running on mainframe, with no API layer. Every integration was point-to-point. New product launches took 6-12 months.
Our Approach
We implemented an API-first wrapper around the core system, then incrementally migrated modules to .NET microservices on Azure. Event-driven architecture enabled real-time processing.
The Outcome
New product launch time reduced from 6 months to 6 weeks. API response times under 200ms. Operating costs reduced by 34% after mainframe decommission.
