What I'm looking for

I'm seeking a Security Architect role where I can apply risk management, threat analysis, and secure-system design to deliver innovative solutions and strengthen organizational security posture.

I've designed security architectures for Prisma MP and Cloud Legion, including infrastructure segregation for Prisma, Payway, and NewPay without operational disruption. I build threat assessments, vulnerability-management plans, and security controls that support business continuity.

Across PwC, IBM Argentina, Encode SA, and public-sector PKI teams, I've led audits, compliance, IAM, digital-signature, cryptographic, and remediation initiatives. I bring more than 20 years of experience across regulated industries, applying NIST, CIS, PCI-DSS, and ISO 27001 to strengthen security posture.
