About Mathieu

Hello,

My name is Mathieu, Sys Admin for over 10 years.

Having evolved in different types of companies (schools / startups / SMEs / multinationals), I have had the opportunity to acquire a wide range of skills and to interact with many collaborators in various fields.

My many years of experience have been marked by periods where I took on responsibilities as the sole person in charge of system and network administration. This allowed me to be efficient, autonomous, and independent.

The startup environment was the most formative for me, as it allowed me to take on multiple roles and manage various projects, from cloud migration to deployment automation.

I have a particular interest in automation, Linux server environments, and the cloud.
I am comfortable in English (spoken or written), having spent 2 years in a multinational company with colleagues from all backgrounds.

Do not hesitate to contact me for your projects, I will be happy to help you achieve them!
