Modernized AWS infrastructure by migrating from legacy EC2 instances to containerized EKS environments, implemented Karpenter with Spot Instances to optimize compute costs, performed EKS cluster upgrades and node group migrations with rolling deployments and zero downtime, defined reliability metrics (SLI/SLO/SLA), integrated Argo CD and GitHub Actions to establish GitOps-driven CI/CD pipelines, troubleshot recurring Jenkins pipeline failures, enhanced observability with Datadog dashboards and alerts, developed and maintained Helm charts, automated infrastructure provisioning with Terraform and configuration management with Ansible, standardized container image scanning and secret management using Vault, and managed Akamai properties, WAF policies, and AWS WAF rules to improve security and performance.

Automated infrastructure provisioning with Ansible and Terraform; migrated to fully automated CI/CD pipelines with Jenkins and Rundeck; designed self-service environments using Vagrant, VirtualBox, and Ansible; automated AWS operations with Python (Boto3) for EC2 lifecycle management, backups, and inventory reporting; built Bash scripts integrated with Jenkins and Ansible to automate patching, configuration checks, and environment validation; managed AWS services (EC2, S3, RDS, Route 53, CloudFront, ElastiCache, IAM, Secrets Manager, KMS, CloudWatch); improved system reliability and incident response; upgraded CentOS base images and implemented automated security patching.

Managed AWS services including EC2, S3, RDS, EBS, ALB, Route53, CloudFront, and Elasticsearch; conducted Datadog-based monitoring and capacity planning; oversaw on-prem IT infrastructure networks, laptops, and office systems; supported backup strategies, patch management, and incident response across hybrid environments; managed IT asset procurement and lifecycle; supported G Suite and Microsoft 365 user provisioning and access management; authored Bash scripts for system monitoring, log rotation, and automated provisioning tasks.
