The Business Problem
Northgate's core banking system offered only nightly batch file integration, blocking real-time mobile banking features and modern fraud detection while a full core replacement was assessed as an 18-month, high-risk undertaking.
The ORYNZEX Solution
Rather than replace the core, ORYNZEX engineered a secure, real-time API layer that translated core banking transactions into modern REST and event streams, enabling new digital products to be built without touching the legacy core.
Architecture Overview
- Change-data-capture pipeline streaming core transactions in near real time
- PCI-DSS compliant API gateway with tokenized transaction data
- Kafka-based fraud detection pipeline processing events as they occur
- Strangler-fig pattern isolating the legacy core behind modern contracts
