Senior DevSecOps engineer embedding security into cloud and platform engineering.
What I'm looking for
I’m a Senior DevSecOps / DevOps engineer with 8+ years building and securing cloud infrastructure across AWS, AWS GovCloud (US), and OCI. I embed security into the SDLC with SonarQube SAST, Checkov IaC scanning, Trivy container scanning, and OPA policy enforcement integrated into Jenkins, GitHub Actions, and GitLab CI pipelines—so non-compliant changes don’t reach production.
I modernize platforms end-to-end, including migrating ~40 workloads from EC2 to EKS with GitOps (ArgoCD), cutting deployment time from ~45 minutes to under 10 minutes across dev, staging, and prod. I also own cloud security governance using Wiz CSPM/CWPP remediation, AWS Security Hub, GuardDuty, and Macie, and I standardize secure CI/CD pipeline patterns adopted by multiple engineering teams. I’m hands-on with Terraform module authoring, Kubernetes (EKS) hardening, GitOps delivery, and observability with Grafana, Prometheus, and OpenSearch—backed by mentoring, incident command experience, and an Active DoD Secret Clearance.
