What I'm looking for

I seek a senior platform or DevSecOps role building secure, scalable cloud/AV infrastructure with strong emphasis on automation, Zero Trust security, and multi-cloud architecture.

I am a Lead DevSecOps Engineer with over eight years designing, securing, and automating large-scale infrastructure, primarily for the autonomous vehicle industry. I architect hybrid and multi-cloud platforms that handle petabyte-scale sensor and log ingestion while enforcing Zero Trust and immutable infrastructure principles.

I have led multi-cluster, multi-region Kubernetes strategies with GitOps (ArgoCD), implemented robust secrets management, and built serverless backends and automated CI/CD pipelines to improve reliability and delivery. My work spans AWS, Azure, GCP, OpenStack, and on-prem environments, with strong focus on security, cost optimization, and operational scalability.

I deliver measurable impact through infrastructure-as-code (Terraform, Terragrunt, OpenTofu), container orchestration (EKS/AKS/GKE), and automation of data pipelines and ML training workflows, ensuring systems are secure, compliant, and production-ready at scale.
