Building, automating, and handling mission-critical, highly secure, and highly available large-scale complex infrastructure.
Provided direct application and user support for any technical issues triggered on RHEL 6, 7 servers.
Building and configuring Virtual Linux Servers using ESXi and vSphere Client to ensure system scalability, optimization, management, and availability needs.
Creatively handle system or networking constraints imposed for on-prem deployments.
Worked with various cloud services including but not limited to EC2 instances, S3 buckets, EBS volumes, Elastic file system, IAM, Cloudwatch, Cloudtrail, ELB, and AMI.
Taking advantage of statistical data generated by Amazon CloudWatch metrics to view, analyze, and set alarms on the operational behavior of your EBS volumes.
Distributing incoming traffic across multiple targets, such as EC2 instances, and containers, in different Availability Zones using Elastic Load Balancing automatically. Monitoring the health of its registered targets, and routing traffic to the healthy targets.
Engineering infrastructure deployment and automation by configuring Ansible to eliminate time-killing manual processes.
Managing patching processes, which include running pre-patching checks, patching implementation, and post-patching checks using Ansible. Troubleshooting post-patch troubleshooting and bringing failed hosts up back to normal function.
Experience with Ansible Tower for Managing job templates and job template workflows, executing simple tasks like adding users, managing malfunctioning services, and resetting passwords on any host or group of hosts in the inventory.
