zverok's space

I don't build systems. I imagine them, then write them.

Buy me a coffee

I am Victor Shepelev aka zverok. Since March 2023, I am part of Armed Forces of Ukraine amidst Russian invasion.

Besides that, I am a software architect at Hubstaff, committer of the Ruby programming language, author of several open-source projects, and writer.

In tech, my main areas of interest are open data and writing lucid code. I approach the code—and the world in general—as a text that we should learn to read and write better. More about me →

Follow me on Twitter and Substack.

→ Support on “Buy me a coffee” (Till the war end, all donations go to Ukrainian organizations supporting the military, or for my own equipment when necessary.)


When my other duties allow, I am writing a blog/substack, mostly dedicated to the programming languages’ evolution, writing and reading code; mostly (but not exclusively) based on my Ruby experience.

Before the full-scale Russian invasion, I was working on an ambitionus Ruby book, titled “41 Ruby Intuitions”. This project is postponed till after the war, but some smaller book is in the works now. Stay tuned.
