About

Cybersecurity professional with nearly 19 years of experience across enterprise security, infrastructure, incident response, technical consulting, customer success, security validation, and automation. I apply artificial intelligence, scripting, automation, and orchestration to solve cybersecurity problems, accelerate investigations, reduce repetitive work, improve analysis, and create practical solutions for security teams. My experience covers threat detection, incident response, exposure management, network and endpoint security, security-control validation, cloud and infrastructure security, technical advisory, and enterprise customer environments. At Picus Security, I support technical discovery, demonstrations, proofs of concept, integrations, deployment planning, and security-validation initiatives across European and LATAM markets. Previously, I spent more than eleven years with FireEye and Trellix supporting strategic enterprise customers, complex investigations, escalations, automation, platform optimisation, and technical training. I combine broad cybersecurity experience with an engineering mindset and a strong interest in applying AI to improve security operations, decision-making, and problem resolution.
