What I'm looking for

I'm looking to architect resilient security programs, solve complex threats, and help organizations adopt new technologies safely through proactive defense, governance, and security culture.

At Sucafina, I architect and deploy enterprise Zero Trust architecture, using Fortinet NGFW micro-segmentation to limit lateral movement and strengthen resilience against advanced threats. I also rebuilt identity defenses through PAM, LAPS, conditional access, and MFA workflows.

I engineer proactive threat hunting and incident response using Microsoft Sentinel, LogRhythm, Wazuh, Nessus, Microsoft Defender, and Intune. My security-awareness initiative reduced user-borne security events by 67% within 90 days, while my work aligns global security posture with NIST CSF and ISO 27001 controls.
