About

A short declaration about who I am and what I do.

I've been coding since I was 14, starting with Minecraft mods in Java, which eventually led me down the rabbit hole of low-level programming with C and tinkering with simple NCurses apps.

Studying computer engineering at UTFPR deepened my love for programming, and now I'm comfortable with C, C++, Python, Go, Rust, Java, and JavaScript, along with tools like LaTeX, PostgreSQL, Redis, OpenCV, NumPy, and Docker.

«Pray as though everything depended on God.
Work as though everything depended on you.»— Saint Ignatius of Loyola

I enjoy the discipline of low-level programming and cryptography, where careful reasoning, attention to detail, and a deep understanding of the underlying systems matter. I see good work as a form of stewardship: a responsibility to use the abilities I have been given with care, humility, and purpose.
