Engineering Narrative

I am

Haris Khurshid

, a Senior Backend Engineer. I started by building backend APIs and business logic, then gradually moved toward scalability, distributed systems, and infrastructure ownership. Over the years, I’ve designed high-volume processing pipelines, distributed storage systems, queue-driven architectures, and cloud-native deployments using Kubernetes and AWS. Today, my focus is backend architecture, infrastructure reliability, and building systems that remain stable under production-scale traffic.
