About
Hi, I’m Sean Thomas, a Senior DevOps Engineer with 10+ years of experience building secure, scalable infrastructure across AWS, GCP, and Azure. I specialize in Terraform, Kubernetes, and CI/CD automation to accelerate delivery while reducing risk.
In previous roles I migrated legacy systems to cloud-native environments, implemented HITRUST-ready infrastructure, and partnered with security teams to embed secure practices. I enjoy mentoring engineers, improving DevOps processes, and collaborating with cross-functional teams to drive velocity and reliability.
