About Me
With three decades of experience in software development, education, and personal transformation, my life’s work bridges the worlds of technology, teaching, and human consciousness. I believe growth happens where knowledge meets awareness — where logic and spirit complement, not contradict, each other.

My professional roots are in the Munich computer industry, where I spent a year with PCS (Peripheral Computer Systems) and several years with ADB (Allgemeine Daten Bearbeitung) before establishing my own business. These years allowed me to work on IBM and NEC mainframes using AS (Application Systems) and to witness — and participate in — the transition to personal computing with the arrival of the first Macintosh, programmed in Apple’s HyperTalk language. For many years now, I have been using Xojo for cross-platform development.

Over the years, I had the privilege of training with many remarkable masters across a variety of martial arts disciplines. Of all those who influenced my path, two left the deepest and most lasting impression: my first sensei, the late Grandmaster Mitsuyoshi Aoki in Judo and my friend - the late Nico Kornhass, World Champion in Kickboxing.

Their teaching went far beyond technique. Through their discipline, experience, and example, they helped shape not only the martial artist I became, but also my understanding of focus, perseverance, respect, and personal growth. Their influence remains an important part of who I am today.
