Node.js Backend System: Observability, Logging & Custom API Architecture

This project is part of my backend learning journey where I focused on understanding how a real server behaves beyond basic CRUD operations. I built a Node.js-based backend system that includes a complete request lifecycle—from routing to response handling—while integrating observability features like request logs, error tracking, and runtime metrics. Instead of relying entirely on frameworks, I explored building core components manually to understand how systems work internally.
