What I'm looking for

I seek a security-focused infrastructure role where I can design and operate resilient cloud and on-prem systems, lead migrations, and collaborate cross-functionally to improve reliability and DR.

I am a Senior IT Infrastructure and Systems Administrator with broad hands-on experience managing Windows and Linux servers, VMware virtualization, Azure and AWS cloud services, Microsoft 365 and Google Workspace migrations, and enterprise networking using Cisco Meraki. I have delivered measurable improvements — including reducing downtime and implementing DR/backup solutions — while partnering with development and third‑party teams to ensure secure, highly available production systems.

I emphasize security-first architecture, having implemented Zero Trust with Cloudflare, deployed advanced endpoint detection and multi-factor authentication, and managed enterprise firewalls and SD‑WAN. I bring practical experience across RMM/ITSM platforms, VoIP, storage technologies (NAS/SAN/DAS), and large-scale migrations, and I am committed to continuous improvement and operational reliability.
