Executive Overview

Processing millions of cross-border financial transactions daily required instant, high-integrity payment reconciliation. Batch-based end-of-day clearing scripts were exceeding night time execution windows, resulting in processing backlogs and costly manual audit reconciliations.

The Challenge

Legacy batch jobs caused reconciliation discrepancies during high-volume trading days, exposing the organization to regulatory compliance risks and delayed settlement reporting.

Architectural Intervention

Replaced legacy ETL batch jobs with a real-time event-streaming architecture utilizing Azure Service Bus, Spring Boot microservices deployed on Azure Kubernetes Service (AKS), and automated Infrastructure as Code (Terraform) landing zones.

Long-Term Results & Value Delivered

Achieved near real-time payment settlement speed, reduced audit discrepancies by 94%, lowered cloud compute infrastructure costs by 38%, and achieved a 100% pass rate on regulatory compliance audits.
