Proven Experience with Mission-Critical Infrastructure
We strictly adhere to all NDA requirements.
Below are anonymized case studies demonstrating our approach to solving high-stakes challenges in the fintech sector.
15x Increase in Payment Gateway Throughput (PSP/Acquiring)
Case 1
Client: Scaling Payment Gateway
The Challenge: As traffic exceeded 100 transactions per second (TPS), the database reached its limits, causing 504 errors and critical latency spikes.
The Solution: Implemented horizontal service scaling and database sharding. Re-engineered queue logic; configured Kubernetes HPA (Horizontal Pod Autoscaler) and read replicas for the database layer.
The Result: The system now reliably handles 1500+ RPS. Latency (p99) dropped from 800ms to 120ms. The infrastructure is architecturally ready for another 10x growth without further modifications.
Security & Compliance (Neobank/EMI)
Case 2
Client: Fintech startup preparing for EU market entry
The Challenge: High risk of EMI (Electronic Money Institution) license rejection due to PCI DSS non-compliance.
The Solution: Engineered a secure Segmented Network Environment; performed comprehensive system hardening and implemented Immutable Logging. Established strict IAM (Identity and Access Management) policies and centralized log management.
The Result: Successfully passed an external QSA audit on the first attempt. The infrastructure is now fully compliant with EU regulatory requirements.
Cost Optimization (FinOps)
Case 3
Client: Money Transfer System
The Challenge: Cloud Sprawl — uncontrolled cost growth and inefficient utilization of cloud resources.
The Solution: Conducted a comprehensive FinOps audit; implemented Spot Instances for non-critical workloads and performed server Right-sizing. Configured precise auto-scaling (HPA).
The Result: Reduced monthly infrastructure costs by 40% while maintaining peak performance. The project achieved full ROI within 2 months.
