I like to think about myself as an old-school indie game developer & hacker. At least, I work in Emacs and single-handedly developed a text-based MMO game — that should say something. However, the definitions of these terms are wide, so you may disagree with me — it is ok.
Since my hobby is the same as my occupation — software development — I have a wide range of expertise, from deterministic game logic in C++ to cloud-based payment systems in Python, and from code analysis to AI-based systems.
If you want to learn more about my interests, just check the most popular tags on my blog — tiendil.org — I mostly write about complex things I've learned and questions I have strong opinions on.
Have a good day. Feel free to contact me by email at a.eletsky@gmail.com or Telegram.
