FinTech Payment Processing Platform
Building a scalable, secure payment platform for modern financial services
The Challenge
A rapidly growing fintech startup was struggling with their legacy payment processing system that couldn't scale to meet increasing transaction volumes. The system lacked support for international payments, had frequent downtime during peak hours, and couldn't integrate with modern fraud detection tools.
They needed a complete overhaul to support multi-currency transactions, real-time fraud detection, and seamless integration with various payment gateways while maintaining PCI DSS compliance.
