Fintech Startup — Payment Infrastructure Modernization
Legacy payment system transformation to microservices architecture. Auto-scaling on Kubernetes, 1M+ daily transaction capacity, and PCI DSS compliance.
Problem
- The legacy payment system struggled with scale and observability under high transaction volume.
- Deployments were risky, and rollbacks took too long.
- Compliance and security controls needed to be visible at service level.
Approach
- Payment, reconciliation, and notification capabilities were split along domain boundaries.
- Autoscaling, secret management, and service observability were designed on Kubernetes.
- Logging, access, and audit trail controls were aligned with PCI DSS requirements.
Outcome
- Critical payment flows became independently deployable services.
- The infrastructure became more resilient under traffic spikes.
- Operations teams gained faster visibility into transaction errors and latency.
