At Robertson College, I'm studying Network Security Technician coursework, including Cisco CCNA: Routing & Switching, network troubleshooting, and Windows Server network services.

As a volunteer Home Network Technician, I configured routers, switches, and modems for network stability. I also created internal and external firewalls and troubleshot connectivity issues between devices and routers.

As a volunteer Home System Admin, I created and maintained device accounts and access restrictions. I used Group Policy Editor, Computer Management, Task Manager, and Event Viewer.

At S&P Data, I provided technical support to end users and diagnosed hardware and software issues. I also documented client interactions to help future agents resolve issues quickly.
