1 - Few lines about me

In 3 words : An IT guy.

I am using GNU/Linux Systems since several years. Currently for work and personnal use, I am on a GNU/Debian 12 system. I also regularly use Windows for work and gaming. I really like the free (libre) software philosophy (from Richard Stallman's movement). However, I am not that extreme in my computing. I use non-free programs almost every day by constraint but also by choice.

I think we can not avoid non-free software in daily life, I'm not a paranoid person who never uses them (or claims to never use them). When I have the choice, I will always choose free (libre) software. Unfortunately, computer science has become more of a business and marketing instead of remaining a common science of sharing and knowledge.

In my job, I mainly do Linux + Windows systems administration and networking (OSI model layers 2, 3 & 4). I am one of those responsible for data security and integrity. I also do scripting (Bash, Powershell, Python) and from time to time web coding (PHP, NodeJS / JS).

I am very careful about data I publish on the internet for my privacy. Big compagnies tend to collect way too much information about people. I usually do not trust them. This page is the only one with information about me.

Here is a non-exhaustive list of software I recommend and use :

3 - Contact me

I am not on social media. I'm not on Facebook, I'm not on ex-Twitter (X), I'm not on Instagram, I'm not on Linkedin, I'm not on TikTok, I'm not on Snapchat, I'm not on Reddit. Social media is stupidizing humans. All accounts on those services with my name are not me.

You can contact me by email to :

I do not refuse to send unencrypted emails via GPG. However, as SMTP is not a secure protocol by design, I usually prefer to use GPG encryption when sending emails. Here is my fingerprint and my key :

75C8 D432 37D4 E900 056E 8517 3F72 770B C56B 3A22
my key (RSA 4096 bits)

Obviously, if you want me to send you an encrypted answer, you need to send me your key.

Note : All my emails using GPG encryption are signed. Please verify the fingerprint.
Note 2 : I will never send sensitive data by email without GPG encryption (e.g. credentials, attachments, localization).
