about me
I'm Martí Castaño, a fullstack developer who loves creating projects that blend frontend, backend, and artificial intelligence. I'm always experimenting with new things — from building my own operating system with Arch Linux to tinkering with servers, home automation, and writing clean, efficient code.
I enjoy tackling challenges with creativity and efficiency, always aiming for clean, maintainable code. I'm particularly passionate about fullstack development, AI applications, and finding innovative solutions across web and systems programming.
