I am a computer engineering and business administration student who has a strong interest in low-level systems and understanding how software works under the hood.

• Student of a double degree in computer engineering and business administration in the University of Granada.
• I love learning about UNIX-like systems and the POSIX standard.
• I also enjoy doing homelab (currently less active).
• Even though I love low-level, I am also interested in AI as a tool.

I participate as an active member of the ETSIIT Tech Club, where we host student-talks or guest-talks at the University of Granada. I have given a talk about Unicode standards, self-hosting LLMs and will be participating in more in the future. We have also participated at the third edition of the AI Congress held annually in Granada.

• Operating systems internals, especially Linux.
• Databases.
• POSIX standards and portability.
• Cybersecurity.

Currently, I am learning about databases and full stack development at University. Low-level topics will be covered in upcoming university courses.

I also use i3wm and sway as window managers along with these distros when they are used for desktop environments. Config files currently private.
