Systems Administrator | Identity | Automation | Infrastructure
I’m a Systems Administrator based in Indianapolis, specializing in Microsoft 365, identity management, automation, and infrastructure. I support multiple client environments across cloud and on-premises platforms, with a focus on troubleshooting complex issues, improving operational efficiency, and building repeatable solutions through automation. Beyond the technical work, I prioritize clear communication and stakeholder alignment, helping drive projects and incidents from discovery to resolution.
Outside of production environments, I maintain a homelab where I experiment with virtualization, networking, monitoring, security, and self-hosted services.
