Project Narrative & Overview
Designed to handle millions of distributed transactions, this API gateway serves as the unified entry point for decoupled microservice clusters.
### Key Capabilities - **Token Bucket Rate Limiting**: Distributed Redis rate-limiter mitigating abuse and enforcing tier-based API quotas. - **Reverse Proxy & Load Balancing**: Weighted round-robin load distribution with automated health checking and circuit breaker fallback. - **Strict Cryptographic Security**: Asymmetric RSA/ECDSA signed JWT access and refresh token authentication flows. - **Developer Documentation & SDK**: Automated OpenAPI 3.0 specification generation with interactive test sandboxes.
