About Me

I'm a Senior Operations Engineer with 4+ years of experience keeping cloud infrastructure running at scale. Currently at Quasar Digital Solutions, I manage 50+ tenant-based ERP environments on AWS for clients like Nextworld and Cloud Inventory — handling everything from Jenkins deployment pipelines to zero-downtime blue-green releases.

Before that, I spent two years at Fini Infotech supporting State Bank of India's critical infrastructure — DR/DC operations, WebLogic patching, and multi-environment management across production-grade AWS workloads.

I hold an AWS Certified Solutions Architect – Associate certification and am driven by building systems that simply don't go down. My toolkit spans cloud, containers, automation, and observability.
