What I'm looking for

I seek a senior cybersecurity role leading SOC/incident response or security architecture where I can drive measurable risk reduction, build high-performing teams, and align security with business goals.

I am a proactive, detail-oriented cybersecurity leader with over 14 years of experience leading SOC operations, security architecture, and cross-functional teams across multiple countries.

In my current role as SOC Lead, I directed a 20-analyst team, driving a 98% improvement in incident response time and reducing high-risk vulnerabilities by 90% through vulnerability management and policy enforcement.

My background includes threat intelligence, EDR deployment, penetration testing, VAPT and red-team engagements, and cloud security (AWS, Azure), with a strong record of achieving compliance to standards like ISO 27001, PCI DSS, NIST and national frameworks.

I hold CISSP and CCSP certifications, have led large-scale SOC automation and awareness programs that cut organizational cyber risk by 95%, and I focus on practical, measurable security improvements that align with business objectives.
