What I'm looking for
I’m a cybersecurity professional with 15+ years of experience across infrastructure security, SOC operations, and enterprise network defense in large global environments. I lead 24/7 Security Operations Center operations, own Priority 1 and Priority 2 incidents, and drive incident triage, investigation, escalation, and closure.
I’m strong in network and cloud security controls, Zero Trust architectures, vulnerability management, and compliance frameworks. From Zscaler Zero Trust (ZIA, ZPA, ZDX) and SIEM operations (ArcSight, Microsoft Sentinel) to ISO/NIST/PCI/GDPR/ITIL-aligned audits and SOC runbooks, I work closely with IT and DevOps to reduce risk with minimal business impact.
