Hey! I'm Arthur — also known as KitsuneSemCalda.
I'm a Brazilian developer who loves technology, Linux, programming languages and building small experimental projects just for fun.
I spend most of my time experimenting with:
- Kernel development
- Systems programming
- Linux customization
- Small tools and utilities
GitHub is basically my playground. If you enjoy OSDev, low‑level stuff or niche programming experiments, you'll probably find something interesting here.
FoxTechWorld is my little blog where I share some thoughts about the nerd, otaku and geek culture...
FoxTune
An experimental tool to optimize Linux systems without installing new packages, focusing on kernel-level configuration tweaks.
Gh-Cleaner
A small CLI utility that removes GitHub repositories using a Bayesian decision model.
FKernel
A hobbyist C++ kernel inspired by SerenityOS, seL4, Minix and the BSD family, focused on clean architecture, System V ABI conventions and modern OSDev practices while avoiding POSIX legacy complexity.
