Message

At Shift4, I lead the Site Reliability Engineering team responsible for AWS production infrastructure and Kubernetes workloads supporting payment processing services. I established SLIs, SLOs, and error-budget practices, and improved observability and incident response, reducing incident detection time by approximately 25% and MTTR by approximately 30%.

Previously, at MX Technologies, I led the modernization and migration of on-premises Kubernetes workloads to AWS EKS, including production workload migrations and database cutovers. Across roles at Milestone Systems and Front, I supported GCP and AWS platforms, automated infrastructure with Terraform, and improved deployment reliability and operational efficiency.
