What I'm looking for

I seek senior-level roles building resilient, compliant network and cloud security architectures with opportunities to lead Zero Trust and global security operations.

I am a Network Security Architect with over 12 years of experience designing, implementing, and managing enterprise-scale security infrastructures across multi-vendor firewall platforms, VPN technologies, and hybrid cloud environments. I have a proven track record in Zero Trust initiatives, high-availability network architectures, incident response, and security policy governance that align security controls with business objectives.

I have led global enterprise security operations, deployed and optimized Fortinet, Check Point, Palo Alto and Cisco platforms, and performed advanced troubleshooting and root cause analysis using packet captures and monitoring tools. My work emphasizes reliability, compliance, and scalable security designs that maintain service availability and reduce operational risk.
