About

I am a seasoned technology executive (CTO/CISO) with 20+ years of leadership experience driving digital transformation, cybersecurity strategy, and enterprise architecture across diverse industries including banking, air cargo, retail, health care, and industrial IT. Known for solving complex challenges and revitalizing broken processes, I’ve led mission-critical initiatives in Fortune 500 and multinational environments — from regulatory transformation to AI-driven threat intelligence. My governance, risk, and compliance leadership ensures that innovation is grounded in strong, scalable frameworks. Whether optimizing multi-cloud ecosystems or pioneering Zero Trust architectures, I deliver solutions built to last. My leadership style blends deep technical expertise with strategic foresight and stakeholder engagement. I thrive in high-pressure situations—frequently called in when previous solutions have failed. Core Expertise: • Cybersecurity Strategy & Zero Trust Architecture • AI, RPA & Emerging Tech Integration • Multi-Cloud Solutions (Azure, AWS, IBM) • Digital Transformation & IT Modernization • CISO/CTO Advisory & Governance • Regulatory Compliance (EU, Financial Services) I’m committed to continuous learning and ethical leadership. My motto: “Important IT architecture and security decisions must be built to last—they require deep, thoughtful thinking.”
