◈ About

I'm the Cybersecurity Services Team Lead at PeakCyber Technologies, with 9+ years of hands-on experience across offensive security, threat intelligence, and strategic cyber defense. My work sits at the intersection of deep technical research and executive-level decision-making — translating complex threat landscapes into actionable intelligence.

Before PeakCyber, I spent 4+ years at Brandefense, where I served as Principal Threat Researcher, Technical Product Manager, and Head of Cyber Intelligence Services — advancing digital risk protection, shaping product strategy, and leading intelligence analyst teams. Earlier, as Penetration Testing Team Leader and Senior Security Consultant at PRISMA CSI, I worked directly with enterprise clients across red team operations and vulnerability assessments.

My mission: bridge the gap between raw security research and real-world defense at scale.
