What I'm looking for

I seek a technical role where I can design and maintain secure, scalable network and virtualization infrastructure, mentor teams, and lead disaster-recovery and monitoring initiatives.

I am a Senior Network, Systems, and Security Administrator with over 12 years of experience building and maintaining secure, scalable IT infrastructures across enterprise environments.

I have hands-on expertise managing firewalls (Sophos, Fortigate, Palo Alto, SonicWall), VMware vSphere/ESXi, Hyper-V, and backup solutions such as Veeam, Veritas, and Altaro.

My background includes VoIP platforms (3CX, Grandstream, CUCM), network core and access switching, storage implementations, and endpoint protection deployments; I have supported 250+ users in production environments.

I also deliver technical training (CCNA, MCSA, Sophos, Veeam), focus on secure infrastructure design, and prioritize operational continuity through monitoring, disaster recovery, and documentation.
