Processing 2M+ transactions monthly with 99.99% uptime and sub-200ms latency across 8 countries.
A growing fintech company needed to replace a third-party payment processor that was expensive, slow, and unable to handle multi-currency transactions. Their existing system had a 2.8% failure rate during peak hours, costing them roughly $340K in lost revenue per quarter.
We built a custom payment processing engine with real-time transaction routing, multi-currency support, and automated reconciliation. The system uses event-driven architecture with Kafka for reliable message processing, Stripe Connect for payment rails, and a custom fraud scoring layer.
Transaction failure rate dropped from 2.8% to 0.04%
Processing latency reduced from 1.2s to under 200ms
Multi-currency support across 8 countries launched
$1.4M in previously lost revenue recovered annually
“We needed a partner who understood both regulation and technology. Heedfx delivered our core processing engine on time — and it handles double the volume we projected.”
