Frequently Asked Questions
Is Node.js scalable enough for enterprise?
Absolutely. With proper event-loop management, clustering, and asynchronous I/O, Node.js handles massive concurrency efficiently.
Do you write tests for the backend?
Yes, I implement rigorous unit and integration testing using Jest and Supertest to ensure the API contracts remain stable across deployments.
