(Markus FEilner, FOUNDER and Owner, Feilner-IT)

For more than 20 years Feilner IT has been helping, coaching and inspiring IT experts, management, leadership, public administration and politicians. We love to provide expert knowledge on digitalisation, the internet and IT in general, Free and Open Source software, standards and data – and always with a close look on your digital sovereignty and sustainability.

Our knowledge comes from a large network of experts, which Markus was allowed to gather in over 30 years of work with Linux and Open Source.

From the inventor of Blameware…

We invented terms like “Blameware“, knowledge management concepts like Agile Recursive Documentation and Onboarding (ARD/ARO), and we bring you new ways of understanding your IT systems, be it by Rubberducking or seeing Digital Sovereignty and Sustainability as a matter of all your system layers – from OSI Layers 1 to 11.

Open Source, Communities, Knowledge & Documentation Management, PR and Technology

In presentations, talks, trainings and coachings we share lessons learned from opensource, linux, community driven development and new ways of collaboration. In our talks and presentations we could show the impact technologies like Open Source, the fediverse, artificiaI intelligence, blockchains and more have on our daily life and business. Again, find many of them on our history pages spanning three decades, but far from complete.
