// The Problem
The challenge
A growing microservices backend had no central point of control — authentication, rate limiting, and request tracing were inconsistent across services.
// The Build
Our approach
We built a centralized API gateway handling routing, authentication, rate limiting, and observability — giving the team one entry point and full visibility.
Node.jsRedisDockerPostgreSQL
// Stack Choices
Why this stack
- 01Node.js for a high-throughput, non-blocking gateway
- 02Redis for token caching and distributed rate limiting
- 03Docker for consistent, reproducible service deployments
- 04PostgreSQL for API-key and policy management
// Outcomes
Results
- Centralized routing and authentication
- Consistent rate limiting across services
- End-to-end request tracing and monitoring
- One secure entry point for all traffic
“We finally have one place to secure, rate-limit, and trace every request. It removed a whole class of operational surprises.”
