What I'm looking for

I'm looking to strengthen enterprise defenses through hands-on security operations, threat monitoring, incident response, and security tool management while collaborating across teams to reduce risk.

At Equinix, I manage and optimize enterprise security platforms across email, endpoint, cloud, and remote access security. I serve as a Proofpoint SME, administer Zscaler and CrowdStrike, and investigate alerts, incidents, and indicators of compromise.

Previously at Spaulding Ridge and Masergy, I strengthened security controls, responded to phishing attacks and network security events, and coordinated containment and remediation with technical teams. I also delivered phishing simulations, security awareness training, customer-facing incident support, and operational documentation.

My background includes web application security assessments at Hewlett-Packard Enterprise using HPE WebInspect, along with vulnerability remediation and security report quality auditing. I hold CompTIA Security+, CompTIA CySA+, CompTIA Security Analytics Professional, and Proofpoint Certified Email Authentication Specialist certifications.
