What I'm looking for

I’m looking for a senior platform/devops role where I can lead Kubernetes + Terraform delivery, strengthen reliability and observability, and collaborate closely with product teams. I want ownership of CI/CD, monitoring, and cloud security at scale.

I’m a Senior Platform Engineer focused on building and operating reliable, cloud-native platforms. In my recent work at InteractiveAI, I’ve driven containerized infrastructure with Kubernetes and Helm, GitOps-style delivery with ArgoCD, and secure service exposure using Gateway API and gVisor. I also own IaC with Terraform and run CI/CD via GitHub Actions, while delivering core GCP capabilities across GKE, Cloud SQL, Cloud Storage, Secret Manager, Cloud IAM, and Artifact Registry.

My career spans senior Site Reliability, DevOps, and technical leadership roles—turning complex infrastructure into dependable systems. At Vonage and other consulting engagements, I worked deeply with monitoring stacks (Prometheus, Grafana, Mimir, Loki, Alertmanager, Alloy), automation (Terragrunt, Jenkins, Bitbucket Pipelines), and production-grade cloud services on AWS (RDS/Aurora Global Databases, EKS, ECS, Lambda, SageMaker, CloudWatch, API Gateway, Step Functions, WAF, IAM). I bring strong development depth too—Golang and Python for platform tooling, plus hands-on applied AI/vector work with Qdrant and pgvector AI—so I can connect platform engineering directly to real product outcomes.
