What I'm looking for

I want a remote-first, autonomous team where I can own AWS platform reliability end-to-end—Infrastructure as Code, CI/CD, Kubernetes ops, and observability—while partnering on incident response and cost optimization through continuous improvement and clear written communication.

I’m a staff-level Senior DevOps / Site Reliability Engineer with 15+ years in software engineering and 5+ years owning AWS cloud infrastructure and developer platforms end-to-end for multi-tenant SaaS products. I design and operate secure, multi-environment setups (staging, pre-prod, prod) with a relentless focus on reliability and cost.

I build Infrastructure as Code with Terraform, CloudFormation, and Terraform Cloud, and I standardize how teams ship by creating reusable Terraform modules and internal CLIs. I also design CI/CD pipelines with GitHub Actions (and Jenkins setup), enabling blue-green deployments, feature-flagged rollouts, and automated rollbacks across multiple services and tenants.

I manage Kubernetes operational reliability, observability, and incident response—using Grafana, CloudWatch, and (occasionally) Prometheus for alerts and dashboards. From on-call leadership to post-incident improvements, I continuously optimize cluster health, troubleshooting workflows, and infrastructure right-sizing so developers can move faster with fewer production surprises.
