Each domain approaches systems from a different angle: human behavior, measurement and learning, digital autonomy, consciousness, sound and technical development.
Human System Protocol™
For people who get stuck in tension, overthinking, control, people pleasing, exhaustion or recurring patterns.
Human System Protocol™ helps make visible which system layer drives behavior and where change can begin.
Digital autonomy
For people who want to become less dependent on Big Tech.
Practical choices for phone, computer, software, cloud, email and digital habits with more control, transparency and autonomy.
Book, consciousness & meaning
IVDAVRA is the domain around my book IVDAVRA and the broader exploration of consciousness, reality, experience and development.
Where the coaching practice mainly looks practically at behavior and system dynamics, IVDAVRA explores the deeper question of who or what the user of the system is.
Audio & tinnitus
Research and development around structured audio, ACRN principles and tinnitus-oriented soundscapes.
A technical and experimental domain for sound, rhythm, patterns and neuromodulation.
Measurement & learning technology
Software I develop for assessments, quick scans, questionnaires and knowledge tests.
Including scoring, result models and feedback for coaching, team development, training and other measurement and learning applications.
Background & Profile
40+ years of experience bridging IT governance, enterprise data architecture, and organizational transformation (e.g., Rabobank, Dutch Tax Authorities).
Connecting complex IT governance with human dynamics on the shop floor through the Human System Protocol.
