This is Who I Can Be for You:
Service Provider Helmsman
Clients commissioning IT projects are often at the mercy of their service providers or talk eye-to-eye. Service providers, on the other hand, have a conflict of interest: providing optimal advice conflicts with their interest in selling more.
With years of experience and communication skills, I find and manage service providers so that you and your project are well positioned for the long term.
Navigator of Uncertainties
The digital world offers many opportunities – which are difficult for non-IT people to utilize. This is especially true when it comes to AI and digital infrastructure. Weighing costs and benefits of IT is particularly challenging, as the real costs are always underestimated.
I would be happy to act as your navigator and help you traverse these uncertainties – so that everyone can enjoy the benefits of the digital world.
Cybersecurity Pilot
For a typical SME, the risk of being hacked is now around 10% per year – especially through AI-supported attacks. This can lead to downtime, loss of reputation, and legal consequences.
I analyze your systems and help you minimize the risk of a breach. And just in case, we work together on exercises and emergency checklists so that you are prepared for anything.

Digital Sustainability & Common Good
As a consultant & service provider, I want to facilitate & create impact, not just do business. It is a personal mission of mine that as many people as possible make a positive contribution to shaping a sustainable future. I am therefore particularly motivated to work with organizations that pursue the Goals for Sustainable Development of the United Nations. I incorporate the following elements of digital sustainability into all my activities:
Handprint: The measurable positive impact of a digital system on one or more of the UN Sustainable Development Goals (SDGs).
Human-centeredness: The alignment of the systems with the goals & needs of the users and other affected persons.
Mindset: The transformation to a sustainable and future-oriented work culture with the aspects of “New Work”, remote work, purpose & common good.
Footprint: The negative impact of a system on the climate, people and the environment. Are reduced, for example, by applying green software principles.
Cybersecurity: The protection of the right to informational self-determination and as well as the confidentiality, availability and integrity of data.
Accessibility: The needs of people with disabilities are considered on an equal footing with other requirements when designing the digital world.
