Stefan’s work has touched fields that at first sight have little in common: music, large-scale open-source migrations, enterprise architecture, fine cuisine, organizational development, and AI. On closer inspection, they share recurring questions about structure, interaction, complexity, adaptation, and how individual parts form a functioning whole.
Across these contexts, his focus is less on individual technologies than on the relationships between components, people, processes, and institutions. His approach is shaped by systems thinking and Kanban: making work and dependencies visible, reducing unnecessary complexity, and enabling deliberate change. He is interested in how complex systems can remain understandable, maintainable, observable, and adaptable — and how technical architecture can support autonomy without losing sight of organizational reality.
He has contributed to initiatives including LiMux and the architectural groundwork for what later became openDesk. His technical work spans AI system architecture, corrective RAG, hybrid retrieval and reranking, observability and provenance, security, reproducible infrastructure, Infrastructure as Code, and deployment across environments from personal computers to data centers and cloud infrastructure. Today he brings these strands together in praivate, a privacy-focused AI platform built around free software, modularity, high engineering standards, reproducibility, and operational control.
Previous speaking engagements include LinuxCon Europe, FOSSASIA, SFSCon, CeBIT, and AI Tech Summit Belgrade. Forthcoming appearances include Big Data Week Bucharest, Kiss the Future Sarajevo, DeAI Summit Malta, and Commons AI Paris.

I’ve been in the IT trenches for over 20 years, but it all started back in 1993 with Turbo Pascal on a 286 AT for a primary school project. Luckily, I eventually upgraded to a 486 DX2, which finally let me run Doom and Heroes of Might and Magic :D.

Since then, I’ve walked the full path: from SysAdmin and .NET Dev to Architect, DevOps, and even a 2-year stint as a CTO in a fintech startup. For the last 4 years, I’ve been a Product Architect at Dynatrace, where I focus on making AWS, Azure, and Google Cloud observability signals actually work for people, not against them.

Outside of work and family, I’m all about "home-keeping" – managing both the physical systems in my garden and the digital ones powered by Home Assistant. If there’s any time left: I’m traveling. The further, the better. :)
