About Me

The DevOps Engineer
You're Looking For

I'm Arun Kumar — a DevOps Engineer at Quess Corp Limited, Kolkata. With 3+ years building production systems, I specialise in AWS cloud infrastructure, container orchestration and CI/CD automation that actually works at scale.

I bridge the gap between development and operations — designing AWS architectures that scale, writing Terraform that provisions in minutes, and building pipelines that deploy with confidence at every push.
