Professional Summary Experienced Virtual Chief Information Security Officer (vCISO) and cybersecurity expert with 25+ years in IT, including 20+ years dedicated to cybersecurity, network defense, and risk management. I help SMBs and fintechs build resilient security postures through strategic guidance, gap analysis, policy development, and hands-on technical execution — delivering enterprise-grade security without the overhead of a full-time CISO. Today my practice extends beyond traditional security into AI Security and LLM Red Teaming. I design defense-in-depth architectures for AI agents (Microsoft Copilot Studio + Azure AI), run adversarial testing against production LLMs (prompt injection, jailbreaks, PII exfiltration), and translate technical findings into executive risk reports aligned to the NIST AI RMF, OWASP Top 10 for LLM Applications, MITRE ATLAS, the EU AI Act, and GDPR. As a Prompt Engineer, I also build high-quality, context-aware, security-hardened prompts, with particular strength in Spanish-language AI content. I hold an MSc in Computer Engineering and have served international clients across multiple industries, making me a strong fit for LATAM, US, and global organizations that need both depth and clear communication.
