Acting as a backend developer at UbiSafe/Orsegups Participações S/A.
Backend developer with experience in implementing projects using x86 Assembly, C, Java and Python, using tools such as git, gcc, nasm, fasm and virtualization tools (see below my open source projects, in the projects section). Experience managing and documenting open source projects. I have experience in using and administering Unix-like systems, such as Linux, FreeBSD and macOS, as well as developing shell scripts. In my spare time, I try to improve myself in Java, C and Rust, in addition to developing an operating system project (Hexagonix, which you can find below, in the projects section), as well as low-level projects. I have a growing interest in Go.
I have technical training in informatics and I worked as an instructor of informatics and technology democratization for students of all ages, with the federal government program Telecentros.BR (Brazil). I worked as a freelancer in software development (using Java and C with integration to MySQL databases) and computer maintenance (laptops and desktops).
I graduated with a bachelor's degree in Biological Sciences from the Universidade Federal de Minas Gerais (UFMG), with an emphasis on Biotechnology and Health, focusing on the areas of Bioinformatics, Biochemistry and Molecular Biology, and I have an academic master's degree (strictu sensu) in Health Sciences from the Instituto René Rachou/Fiocruz Minas (Fundação Oswaldo Cruz).
I am interested in preservation, documentation and emulation of historical software, having a large collection of operating systems collected over the years.

osdev | 2021-currently
- osdev is a project that aims to catalog and obtain more information about active open source operating system projects, as well as providing selected material that can help in the development of independent operating system projects. Therefore, all projects are classified according to operating system family, target architecture, whether they are available on GitHub or not, whether they are active (with commits less than 4 years old) and software license. In addition, the repository seeks to raise and organize historical material on the most used operating systems or those that revolutionized computing, such as UNIX.

Netuno OS | 2012-2014
- During 2012, motivated to learn more about how a modern operating system works, I started to develop a small and simple Linux distribution, choosing to maintain a command line interface. For that, I followed the steps proposed by the Linux From Scratch project. The result was Netuno OS, an operating system based on the 2.6 series Linux kernel, standard tools and utilities. There are no sources other than those available for the packages used, so a repository had not been created at the time. What was left of it was an installation image of the system, approximately 192 Mb, dated 2012 and updated in 2014. At the moment, I also developed some kernel modules to study the interfaces and use of the /proc directory.
