Systems Administrator

Hello and welcome to my page. There's not much here other than a brief summary about me, my resume, and a contact form.

I'm an experienced IT professional with 12 years as a Systems Administrator in the medical device industry, followed by 6 years in a DevOps role at a managed service provider. My core expertise includes infrastructure-as-code (Terraform, CloudFormation), automation (Ansible, scripting), and monitoring (Nagios XI, OCI Observability and Management). I've managed Linux and Windows servers across on-premise, AWS, and OCI environments, supported end-users, and contributed to software development teams as a tester. I particularly enjoy troubleshooting technical issues and providing practical and reliable solutions.
