I’m an IT Infrastructure Engineer, performing audits, administration, and engineering across various fields of IT infrastructure.

My personal servers run Unix-like systems (BSD, Linux, Solaris), and I use Debian as my desktop OS. I develop in C, C#, Lua, and Python 3 for both professional and personal needs. I also write shell scripts (I'm a Zsh enthusiast) and am a fan of Vim and Git.

I also like to create SVG icons with Inkscape and play with CAD softwares (I'm definitively not a good CAD engineer but it is fun and useful).
