Context & Pain Points
Operating a high-scale transactional fintech platform required strict PCI-DSS compliance, sub-50ms database operations, and multi-tenant security structures to protect sensitive financial records.
What We Had To Solve
- Ensuring strict isolation of tenant banking profiles and payment records.
- Achieving sub-50ms database write latencies for real-time transaction processing.
- Configuring secure, encrypted credentials and key rotation structures to satisfy external auditing bodies.
How We Built It
- Deployed containerized microservices on AWS ECS Fargate in highly private networks with dedicated security groups.
- Provisioned Amazon Aurora PostgreSQL clusters with multi-AZ replication, optimizing query indexing and session scaling.
- Integrated AWS KMS keys with automated annual rotation for envelope encryption of all transactional databases.
Outcomes That Mattered
100% Auditing Success
Zero critical findings across PCI-DSS external security evaluations.
Transaction Scalability
Sustained thousands of concurrent transactions with sub-50ms API request responses.
Full Envelope Encryption
Safeguarded 100% of consumer profiles and financial histories with KMS-backed encryption keys.
Outcome
Built a production-grade AWS ECS Fargate environment that satisfied 100% of PCI-DSS compliance audits, integrated Aurora PostgreSQL replicas for high read performance, and used KMS keys for envelope encryption.
