Senior depth without the big-machine engagement.

Since 1980 I have worked across radar systems, NATO command infrastructure, regulatory analysis, WordPress operations, local AI pipelines and visual communication. The range is not a contradiction. It is the product: I can think myself into unfamiliar problems, build what is needed, and hand over a usable result.

Why clients bring me in

  • A problem is too complex for a simple freelancer task, but too small for an agency.
  • The work needs senior judgement and hands-on delivery in the same person.
  • Architecture, AI, regulation, infrastructure or communication overlap.
  • The result must be documented clearly enough to stand without me.

Working principles

  • Clarity over complexity — prefer simple solutions, use complex ones only when necessary.
  • Outcome over activity — no busywork for its own sake.
  • Transparency — you always know what is happening and why.
  • No vendor lock-in — open standards, documented decisions.
  • Handover built in — every engagement ends with documentation that works without me.

Collaboration

  1. Clarify context

    What is the starting point? What needs to be achieved? Who are the stakeholders?

  2. Analyse

    Technical inventory, risk assessment, document dependencies.

  3. Implement

    Pragmatically and in traceable steps. Regular feedback.

  4. Hand over

    Documentation, knowledge transfer and recommendation for next steps.

Recognition

  • Formal nomination by the German Ambassador to the NATO Council (2008)
  • Certificates of Appreciation from NCI Agency, NACMA, C3 PWG, and the NATO Air Traffic Management Committee
