NexusPay - Next-Gen Fintech & Payment Gateway Core
High-throughput payment orchestration engine processing $40M+ monthly transactions with sub-second settlement and PCI-DSS compliance.
Project Overview
NexusPay was engineered by Hemtrix to provide scalable merchant checkout APIs, automated fraud anomaly detection, and unified banking rails.
Legacy payment gateways were failing during peak flash sales with checkout latency exceeding 8 seconds.
Hemtrix engineered an asynchronous event-driven core in Laravel, Redis cluster, and Go microservices with multi-region AWS failover.
Measured Business Impact
Achieved 99.999% uptime, reduced checkout latency to 420ms, and scaled through Black Friday without a single drop.
