CTO | AI Agent & Cybersecurity Expert | AI for Security · Security for AI

I have spent more than 25 years building cybersecurity companies and products, from PKI, cryptography, and Secure OS to endpoint, embedded/IoT security, security automation, NDR, and AI agent runtime security.

Today, as CTO at Fastpace, I work as an AI-native cybersecurity product architect. I define the problem, product requirements, system architecture, threat model, evaluation criteria, and operating model, then orchestrate AI coding agents to implement, test, document, and validate working systems.

My focus is making AI agents useful in real operations without losing control, explainability, or accountability.

Current focus

  • AI for Security — Agentic SOC, AI-assisted security operations, threat analysis, and automated response
  • Security for AI — Runtime policy enforcement, tool-call governance, prompt-injection and PII controls, human approval, and audit trails
  • Network Detection and Response — nDPI, Zeek, Suricata, MITRE ATT&CK, behavior analytics, threat hunting, and forensic triage
  • Vulnerability and Asset Management — CVE, CISA KEV, EPSS, authenticated scanning, and enterprise exposure management
  • Security Automation — Phishing analysis, enterprise mail intelligence, ransomware detection, and agentic IT operations

Featured projects

How I build

Rather than working as a traditional hands-on software developer, I combine deep security-domain expertise, product judgment, specification-driven architecture, and AI-agent orchestration to take systems from problem definition through validation and deployment.
