RinggitPay, a client of ours, needed a way to perform transaction anomaly detection in a manner that was extensible and cost effective. We created a solution that utilised several server-less components from AWS including API Gateway, AWS Lambda and a few more. This service currently detects potential fraudulent transactions performed by merchants and customers and alerts teams based on the rules applied on those anomalies.

All of this was done using AWS Cloud Development Kit (or AWS CDK) as infrastructure as code layer. Further, this was all deployed automatically using AWS built in CI and CD offerings.
