As a seasoned Cybersecurity Technical Lead with over 13 years of experience, I specialize in safeguarding complex infrastructures through advanced Security Operations (SOC), Vulnerability Management, and proactive threat monitoring. My expertise spans a wide range of cutting-edge security tools and technologies, including QRadar, Splunk, Google Chronicle, RSA Archer, and Rapid7, enabling me to design and implement comprehensive cybersecurity strategies that align with business objectives.

I am passionate about building resilient cybersecurity systems, enhancing threat detection capabilities, and ensuring regulatory compliance (PCI DSS, HIPAA, ISO/IEC 27001). I’ve successfully led cybersecurity teams in high-stakes environments, overseeing everything from vulnerability assessments to incident management for major organizations across industries.
