Who I Am
About Me

I'm an IT professional with 3+ years of hands-on experience in systems administration, network infrastructure, and endpoint security. I hold CompTIA Network+ and Security+ certifications and work daily with Active Directory, DHCP, SentinelOne EDR, Fortinet FortiGate, and NinjaOne RMM. Before moving into IT I worked as a CNA and that background genuinely shaped how I approach this work: attention to detail, staying calm when things go sideways, and taking documentation seriously.

At Columbia County School District I manage infrastructure across 15+ sites, helped lead a full Cisco-to-Juniper migration, and use AI tooling to speed up alert triage and cut down on repetitive tasks. I care about doing the job right and keeping systems running reliably for the people who depend on them.
