IndiaWhat I'm looking for
I’m an AWS Cloud Infrastructure Engineer with 6 years of experience managing enterprise production environments across AWS and hybrid infrastructure ecosystems.
I support mission-critical workloads in 24x7 environments, delivering strong operational stability through proactive monitoring, incident management, high availability architecture, and cloud migration execution.
In my roles, I supported 400+ Oracle database workloads across on-premise and AWS EC2, consistently meeting 99.9% uptime SLA targets. I also owned backup and recovery using Oracle RMAN, and coordinated P1/P2 outage resolution with clear stakeholder communication.
I bring hands-on engineering depth through Terraform-based Infrastructure as Code, AWS CloudWatch observability, and migration work using DMS/SCT. I’ve also improved operational efficiency by reducing recurring deadlock/blocking incidents by ~35% through systematic SQL scripting, explain plan analysis, and performance tuning.
