-        I am [your description — e.g. developer, designer, educator...] with an interest in [topics you focus on].

+        Developer by day, father of three curious kids, and my wonderful wife's husban all day long. My name is Vladimír and I live in a pleasant chaos where, between debugging code, we tackle questions like why the sky is blue, how black holes work, and whether math can be learned through play. Because we believe curiosity is a better foundation than a curriculum, we homeschool our children — and honestly, they teach us just as much as we teach them.

+        As a developer, I've always loved the act of writing code itself — that moment when the machine starts to listen. These days, AI is increasingly taking that joy out of my hands.

I enjoy exploring new territories — virtual ones, mental ones, and the world at large.
