Hi! I'm Ruotong Guan, you can just call me Carlotta/Selkie. Currently I'm a graphics-focused programmer, but also much more than that.

Besides programming, I'm also an artist, a manga lover, a cosplayer, and a gamer.
These passions shape how I see the world, and how I bring creativity into technical challenges. Whether it's drawing or debugging C++, I love exploring beauty — both visual and structural.

I'm always learning, always building, and always trying to explore the world.
