What I'm looking for

I am looking for opportunities that foster innovation and collaboration, with a focus on cloud technologies and automation.

I am a Senior DevOps Engineer with a strong track record of building reliable, scalable infrastructure and leading cloud migrations for enterprise and high-growth tech environments. My expertise lies in Kubernetes, AWS, Terraform, and CI/CD tools like ArgoCD and GitHub Actions, with a focus on automation, cost optimization, and security compliance.

Throughout my career, I have been known for improving system resilience, reducing deployment time, and driving operational efficiency across cross-functional teams. At United Airlines, I redesigned CI/CD pipelines, introduced Kubernetes-based infrastructure, and automated disaster recovery procedures, significantly cutting operational costs and enhancing compliance. My experience at DoorDash and FedEx further solidified my skills in infrastructure management and cloud optimization.
