Engineering Leadership · Enterprise Architecture · AI

I believe in the power of people working together — especially in times when technology and AI are evolving faster than any one person or team can keep up with.

With over 25 years of IT experience, including 15 years in the financial sector, I combine engineering and architectural experience with a passion for developing people, sharing knowledge and building technology that creates lasting value.

What I do

Technology is a team effort.

I lead software engineers and contribute to enterprise technology and AI initiatives, including knowledge retrieval, cloud architecture and agentic platforms.

My focus is on enabling strong technical leaders, connecting expertise across organisational boundaries and creating shared capabilities. Good technology decisions need both deep expertise and the willingness to collaborate.

Beyond work

Curiosity beyond technology.

I'm interested in economics, monetary systems and the way complex systems influence our society. I enjoy questioning established assumptions and exploring different perspectives.

That interest has also led me to public discussions, personal writing and a contribution to the documentary Oeconomia.
