Hello!

I am a thinker driven by curiosity, seeking to understand the world. As a financial risk analyst, psychologist, and philosopher, I work in these fields and synthesize knowledge from psychology, philosophy, evolution, cosmology, finance, and ancient history in my books to offer readers a unique perspective.

I am not a fiction writer; my works focus on delivering maximum insight with minimal words, rather than unnecessary motivational phrases or fantasy worlds. Sometimes my books present familiar ideas from a new angle, and sometimes they pose unconventional questions.

Some of my works include:

Money Doesn’t Change, But You Can – A journey into financial and personal awareness.

The Mind’s Operating System – Analyzing personal transformation ...more

Children of Jotunheim

Children of Jotunheim: A Philosophical and Epic Sci-Fi Journey That Reflects Humanity’s Soul
“To be born does not mean to obey.
If I breathe, I want to live by my own choice.”

What begins as a desperate escape from a dying Earth slowly transforms into an unforgettable confrontation—not just with the unknown or the future, but with ourselves.
