Hi Maintainer! I'd like to work on this issue if it's still available.

I have experience building secure backend services with TypeScript/NestJS, API gateways, authentication, rate limiting, and microservice integrations. For this task, I'll design and implement a robust API gateway that routes requests to the appropriate services while enforcing JWT/OAuth authentication, applying rate limiting, handling CORS, exposing health check endpoints, and providing comprehensive request/response logging.

I'll keep the implementation modular and aligned with the existing architecture by reusing established middleware and shared utilities where appropriate. I'll also implement resilient request handling, including a circuit breaker pattern and request transformation layer, ensuring the gateway remains reliable under failure conditions. To validate the implementation, I'll add comprehensive tests covering routing, authentication, rate limiting, health checks, logging, circuit breaker behavior, and error scenarios so the feature is well-tested and maintainable. Before submitting the PR, I'll verify that linting, builds, and the full test suite pass locally, and I'll include "Closes #" in the PR description.
