What I'm looking for

I’m looking to keep owning automated AWS/Azure infrastructure and secure, Left Shift CI/CD—plus Kubernetes workload orchestration with ArgoCD/Argo Rollouts—using Terraform, Sentinel, and strong monitoring in a team that values automation and reliability.

I’m a Senior DevOps Engineer with 6+ years of total experience, focused on AWS cloud infrastructure and Enterprise CI/CD migration. I’ve led large-scale modernization efforts that improved deployment lifecycles and reduced technical debt, including migrating 20k Jenkins pipelines to ~7k standardized pipelines.

I build secure, policy-driven delivery pipelines through Left Shift security scanning with GitLab/GitHub native templates and HashiCorp Vault integration. I also develop governance using HashiCorp Sentinel for automated infrastructure compliance and operational reliability.

I automate infrastructure provisioning across AWS (EC2, ECS, EKS, Lambda) and Azure IaaS (VMs, Storage, Databases, Key Vault) using Terraform Cloud, while using Splunk and Prometheus for proactive monitoring. On top of that, I engineer GitOps and workload orchestration with ArgoCD and Argo Rollouts, and I modernize automation through Shell/Bash/PowerShell scripting, Ansible playbooks, and IaC patterns.
