At TEBillion Systems, I manage AWS infrastructure across production, staging, and pre-production environments supporting application, database, Windows, Linux, and bastion-host workloads.

I automated monthly OS patching with AWS Systems Manager, reducing manual effort by over 90%, and built CloudWatch dashboards and alerting for proactive issue detection. I also manage backup, disaster recovery, IAM policies, and performance troubleshooting across Linux and Windows servers.

I use Terraform to automate MongoDB backup and retention workflows, and I developed an event-driven CI/CD failure notification solution with AWS Lambda, EventBridge, and SNS. I work closely with development teams on deployments, release management, production incidents, root-cause analysis, and corrective actions.

My projects include production-grade EKS infrastructure with Terraform and Argo CD, where GitOps automation reduced deployment lead time by 70%. I have also built DevSecOps scanning pipelines and multi-region AWS infrastructure that achieved 99.99% platform availability.
