About Me

I’m just a boy who’s passionate about computers :3

I do security research, and in my free time, I enjoy petting cats and playing games.

I used to play Valorant, but these days I play a lot of Minecraft. You may also know me as an active SCP:SL player, since I was quite active in the community from 2023 to 2025.

I’m also kind of a law nerd, so I follow legal news from different countries and analyze various legal issues.

I love posting about interesting stuff I find, so check out my blog if you’re interested :3
