At Mimir IT Consultation Services, I set up and manage Microsoft 365 environments, migrate email and data, and configure Azure infrastructure. I also work on device compliance and SharePoint and OneDrive deployments.

At On Time Tech, I administered MSP business systems and endpoints, including cloud, security, backup, and network systems. The role covered 1,500 endpoints.

Across my IT work, I’ve supported infrastructure, systems administration, and network operations. I also co-founded Happy Planet Industries, where I worked on hydroponic systems, solar installations, and sustainable food production.
