What I'm looking for

I’m looking for a platform-focused role where I can lead Kubernetes and Internal Developer Platforms using GitOps and policy-as-code, delivering measurable reliability (SLIs/SLOs), stronger security/compliance, and FinOps-driven cost optimization with a pragmatic engineering culture.

I’m a staff-level Senior Platform Engineer with 10+ years architecting enterprise-scale cloud infrastructure across AWS, Azure, and GCP. I specialize in multi-account Kubernetes platforms, GitOps, DevSecOps, and FinOps—turning governance and automation into measurable reliability and developer velocity.

Most recently at Amazon, I architected and governed a multi-region, multi-account Kubernetes Internal Developer Platform serving 30+ teams at 99.99% availability. I built a Terraform-based AWS landing zone that cut provisioning from 5 days to 2 hours, delivered ArgoCD/Helm GitOps with 3× deployment frequency, improved security via IRSA and policy-as-code (OPA/Checkov/tfsec), and reduced MTTR 35% using a Prometheus/Grafana/Loki/OpenTelemetry observability stack—while driving $1.2M+ annual cost savings.
