Profile

Empowering Innovation & Driving Global IT Success

I help organizations unlock their full potential through strategic IT leadership, hands-on innovation, and measurable business outcomes. Today, much of that work is about augmenting or replacing traditional processes with production-grade AI systems that actually ship — built on top of more than two decades of IT transformation experience.

Why partner with me?

  • Global experience: Over 20 years leading IT transformation and innovation for multinational organizations across Europe, the USA, and Asia.
  • Business impact: Delivered measurable results, including a 35% boost in operational efficiency, $3.5M in annual cost savings, and 99.98% infrastructure uptime.
  • Production AI delivery: Not just strategy — real AI products operating in the wild. Built and run a multi-tenant agent platform serving thousands of users, published consumer AI mobile apps on the App Store and Google Play, document-intelligence pipelines that replace manual back-office work, and conversational onboarding assistants that replace form-based workflows.
  • Modern expertise: Specializing in agentic AI platforms, vision and document intelligence, conversational workflow automation, cloud migration, cybersecurity, and data & analytics — with strong opinions on model selection, cost control, safety, and human-in-the-loop design.
  • Leadership & mentoring: Built and managed high-performing, distributed teams; coached IT managers and executives; and bridged the gap between technology and business strategy.
  • Trusted advisor: Recognized for clear communication, intercultural leadership, and a hands-on approach that scales teams and platforms from one founder to global operations.
Perspective
"I take the same engagements founders used to reserve for a full-time VP — at a fraction of the overhead, and with a builder's hands still on the tools."

Most fractional CTOs choose: advise or build. The strongest engagements require both — strategic judgment in the boardroom and operational credibility on the keyboard.

Speak with my AI assistant before we speak in person.

Have a question about my background, past engagements, or whether we'd be a fit? My AI assistant is available at the bottom of every page — or open it directly below. It is still learning — thank you for your patience.
