Undisclosed Fintech Payment Platform

One of Southeast Asia's leading fintech companies was spending significantly more on AWS than necessary, with database and compute resources left over-provisioned from rapid growth. Deployment pipelines lacked automation, increasing the risk of human error in a PCI DSS-regulated environment. Serving users across Indonesia required low-latency infrastructure but the primary compute region was in AWS Oregon — far from end users.

We conducted a full infrastructure audit and cut monthly AWS spend by USD $5,800 through rightsizing compute and database instances and eliminating waste. We designed and built battle-tested Terraform modules for Amazon RDS and Elasticache — eliminating 100% of manual provisioning toil and establishing us as the internal Terraform SME. To ensure compliance, we maintained PCI DSS posture throughout and contributed to an enterprise-level multi-region disaster recovery strategy with validated RTO/RPO metrics. We then executed a region migration from AWS Oregon to Jakarta and Singapore, achieving a 50% reduction in API latency for regional users.
