About me:

I am an engineer in France and Canada, specializing in cybersecurity.
I am convinced that security should be accessible to everyone, understandable, and at a justified price.

I worked for a large digital company after my studies. Today, I prefer the authenticity of customer relationships.

I learned to code and work before the advent of LLMs, so I am not dependent on them.

I would be delighted to hear about your projects.
