- When I was 13, my only wish was to have my own MMORPG.
- This is when I picked up my first programming book, Symfonia C++ by Jerzy Grębosz.
- I'm completely self-taught, though I did enroll at the top3 high school in the country (at the time).
- I began writing Hypersomnia once I turned 18. I'm now 28.
- At 19 I went to work as a junior C++ programmer instead of going for a higher education.
- I later went on multiple year-long breaks from work to focus on writing Hypersomnia, whilst living from my savings.
- Since 2020, I became passionate about investing, thanks to which my savings lasted way longer than they'd otherwise.
- My financial decisions now let me focus 100% on Hypersomnia.
- I use Arch Linux, and I wrote Hypersomnia in NeoVim, without autocomplete (but with 21 other plugins - vim-easymotion being my favourite).
