\section{Open Source Projects}
\begin{itemize}
\vspace{2mm}
\item \textbf{SLAE}: Security Linux Assembly Expert course assignments. All seven assignments accomplished with
merit. This project resulted in the creation of some of the smaller shellcodes of its kind
in the world. Smaller than those present in Metasploit. Eg. Tiny Shell Bind TCP and Shell Bind
TCP Random Port (latter is unique of its kind).\newline

\item \textbf{radix}: A kernel project for academic purposes that uses grub and its multiboot support.
It is maintened by radix-kernel organization.\newline
(\url{https://github.com/radix-kernel/radix})\vspace{1mm}

\item \textbf{uzumaki}: A simple Emacs buffers cycler that optimize the swapping between open buffers in that famous
editor.\newline
(\url{https://github.com/geyslan/uzumaki})\vspace{1mm}

\item \textbf{C in Fork Book}: It is a pilot project to write a book about the C programming language addressing
beginners in computers. It will be originally written in Portuguese but with plans
to be translated into English.\newline
