Welcome! My name is Avish, and this is my site for things I make or find interesting. I’m 22 years old, born and raised in London, and am currently working as a quantitative researcher in Amsterdam.

In my free time, I enjoy programming, reading, making and solving puzzles, social deduction games, board games, travelling, doing maths, and more. Online, I often go by AK1089, after my initials and favourite number.
