🏴☠️ Senior asm2bf developer. Hobbyist programmer since 8 years, low level & esolang fan. Chess player.
I'm programming commercial, real-world widely used applications in Brainfuck. I made the best Seed generator in existence (possibly, at least it's better than feersum's one). I've proven Seed Turing completness.
I can also program Malbolge.
NOTE: 21.05.2020, I've hung up my activity on CGCC. I won't post this many answers anymore and possibly I'll post some challenges every once in a while. I already put too much time and effort in answering and crafting challenges, for me it's finally time to move on.
