About Me
From curiosity
to commitment.
I'm Sagar Karki — a Cloud & DevOps Engineer in the making. My journey started with a simple question: "how does the internet actually work?" That curiosity turned into a deep passion for Linux, containers, cloud infrastructure, and automation.
I'm currently taking on the 100 Days of DevOps challenge — solving real infrastructure problems daily on live servers. Every command I run, every mistake I make, every concept I learn gets documented here.
