The Problem

The bank's fraud detection ran on overnight batch jobs against a legacy on-premise warehouse, meaning fraudulent transactions were often flagged a full day after they occurred.

The Solution

We designed and built a streaming data platform on Azure using event-driven ingestion and a Databricks lakehouse, replacing the nightly batch process with real-time transaction scoring.

The Outcome

Fraud signals now reach investigation teams within seconds of a transaction, with the platform scaled to handle national peak-hour transaction volume without added infrastructure cost.
