A complete AI-driven B2B payment gateway built from scratch, with fraud detection algorithms processing $50M+ every month.
Nexus Pay replaced a legacy processor with a white-label gateway the client could put in front of enterprise customers, built, tested and deployed in 45 days.
The client relied on legacy payment processors that took 5% of their margins and lacked modern B2B features like bulk invoicing, automated reconciliation, and intelligent fraud detection.
They needed a distinct, white-label gateway built fast, to onboard the enterprise clients already sitting in their pipeline.
In exactly 45 days our full-stack team engineered and deployed a scalable Node.js microservices architecture.
We integrated a custom ML model to detect suspicious transaction velocity in real time, built an intuitive React dashboard, and wrapped the system in an AES-256 encrypted database layer compliant with PCI-DSS standards.
Real-time anomalous pattern recognition powered by customised TensorFlow models handling 1,000 transactions per second.
Node.js and Express services orchestrated via Docker and AWS ECS for effectively limitless scale and 99.99% uptime.
A frontend command centre built in React, using live websockets for instant reconciliation alerts.
End-to-end payload encryption, multi-factor authentication, and automated daily database backups to Amazon S3.
Since launch, the platform has delivered:
