About me.

I have spent over 23 years keeping critical systems running for people who depend on them: students, teachers, and public administrators across Brazil. At SME Fortaleza — one of Brazil's largest municipal education departments — I manage an infrastructure of approximately 200 VMs and lead a team of analysts supporting over 266,000 active accounts daily, managing more than 57 TB of corporate data.

My work spans VMware virtualization, Windows Server and Linux administration, network security with Fortigate, CheckPoint SASE, SentinelOne EDR, F5 BIG-IP, and Wazuh SIEM/XDR, DNS, DHCP, VPN, and VoIP/SIP operations. In recent years I have built AI-powered internal tools that my team uses every day: a Zabbix-integrated monitoring chatbot, an Active Directory query interface, and automation scripts that provision and manage over 266,000 Google Workspace accounts. I hold postgraduate degrees in IT Governance and AI applied to Public Sector Management.

In 2026, I attended RSA Conference in San Francisco, focusing on AI-driven threat detection and identity management alongside global cybersecurity leaders. If you are looking for someone who understands infrastructure from the cable to the boardroom decision that depends on it, let's connect.
