About Me

Mon, 01 Jan 0001 00:00:00 +0000

Arian Svirsky

Senior DevOps Engineer — Building production infrastructure since 2014.

Background

I’m a DevOps engineer with deep expertise across the entire infrastructure stack — from Linux kernel tuning to Kubernetes cluster architecture, from CI/CD pipeline design to cloud cost optimization.

Over the past decade, I’ve worked across startups and scale-ups, building systems that handle millions of requests and maintain high availability. My approach combines automation-first thinking with practical engineering — every system I build is designed to be reproducible, observable, and self-healing.
