PROFILE
I work my way into difficult technical situations.
I’m Claus Siebeneicher. I am your direct contact for independent technical advice, ideas and second opinions. My practical experience helps me connect the technical detail with the wider system. Any hands-on contribution is agreed separately, with a defined scope.
Personal collaboration within a cooperative framework
I work within the SMartDe eG cooperative. If you commission work, SMartDe eG can be your contractual partner; I personally provide the technical advice and agreed contributions. We agree the scope and deliverable for the specific question at hand.
Experience that translates into practical work.
I have worked on technical systems since 1980. The work has changed—from radar and automated testing through architecture and interoperability to web platforms and AI-supported workflows. The constant is the need to understand what a system actually does and how a decision can be justified.
I bring technical experience and a wider view of the system to your questions. That is especially useful when a question crosses disciplinary boundaries.

Beyond conventional IT
My work also includes AI-assisted visuals and theatre posters, virtual galleries in Unity, and personal drone and photogrammetry projects. This is not another product catalogue. It gives me different ways to look at a technical problem.
Let’s discuss your question.
Tell me briefly what you would like to clarify, which ideas you want to explore or where you need a second opinion. We can then agree a useful starting point and a defined scope.
