What I'm looking for

I seek a hands-on IT role where I can lead infrastructure projects, improve security and reliability, mentor teams, and drive scalable solutions in an education or enterprise environment.

I am a seasoned System Support Engineer with extensive experience in system and network administration for K12 schools and large user communities, managing environments supporting over 3,500 students and 400 staff. I have implemented network architectures, firewall policies, backup solutions, tenant setups for Microsoft 365 and Google Workspace Education, and performed LAN/Wi‑Fi planning and fiber/Ethernet cabling.

I lead technical teams to maintain uptime and security, handle procurement and IT budgeting, and deliver measurable improvements through certifications and process-driven operations. My hands-on expertise spans Fortigate, SonicWALL, Cisco routing and switching, Acronis backup, Active Directory, proxy/antivirus solutions, and incident management systems.
