About me

20+ years of technical leadership in mission-critical legacy modernizations - from banking to healthcare to public safety.

My specialization: complex system transformations with special technical or regulatory challenges

As a hands-on solution architect, I combine a deep understanding of legacy systems with modern AI integration. Instead of just advising, I architect and implement - from the first line of code to the productive go-live.

Especially in regulated environments (KRITIS, compliance requirements, 24/7 availability), my solutions have led critical transformations to success. When standard consulting reaches its technical limits, I take over.
