🖖 My name is Dmytro Parfeniuk (born 1998). Married. Live in Kyiv. Working professionally in tech since 2019.

I like computer science, complex systems, physics, biology, philosophy.

Not my cup of tea: Theory-of-everything (TEO), sports, games.

Reason for this blog: writing gives more time to reason about things during the formalizing process. Also, I noticed that if I let the information go, I make the room for new information.
