NovaBank API Gateway

Overview

NovaBank needed a high-performance API gateway to sit in front of their core banking services, handling authentication, rate limiting, and routing for their growing fintech ecosystem.

The Challenge

The gateway needed to handle sudden traffic spikes (up to 50k requests/second) with sub-10ms latency, while enforcing strict security policies and providing full observability for their compliance team.

Our Solution

Built in Go for maximum performance, deployed on Kubernetes with horizontal auto-scaling. Redis handles distributed rate limiting. Full request/response logging feeds into their compliance dashboard in real time.

Results

• ✦2M+ daily requests handled reliably
• ✦P99 latency under 8ms
• ✦Zero security incidents since launch
• ✦Auto-scales to 50k req/s during peaks
