I occasionally do LeetCode, my solutions can be found here
climenu - A little application for creating tui menus, nice for organizing shortcuts.
svgshift - Quick program to shift colors in svg files, created this to fix up my desktop theme a little since GIMP was a bit confusing.
gnomefavs - cli utility for creating GNOME task bar presets, kind of like focus modes, but for the task bar.
permutations - really simple cli utility that generates permutations, I use this to bruteforce PAYDAY 3 keypads.
ratcp - rsync if it could only recursively copy directories, and had no versatility whatsoever.
cnake - snake game.
Teordle - command-line wordle.
