About

Passionate, curious, and comfortable with a wide range of IT solutions, I would like to boost my career abroad, particularly in Japan, where I have previously worked. Always ready to take on new challenges, I would like to join a motivated team where my skills will be appreciated.

Resume

From a young age, I have always been drawn to computers and new technologies. Naturally, I pursued a "BTS IG" followed by a "Licence Pro R&T" (see the Education section). This allowed me to complete a year of apprenticeship within a company (Gustave Rideau), where I had the opportunity to explore various IT solutions. I then stayed with this group for four years as a system and network administrator. During these four years, I was responsible for a large part of the group's information system. However, the desire to broaden my horizons motivated me to go abroad for several years, which allowed me to greatly improve my level of English. Today, I am once again working as a system and network administrator for a large group (Vinci), particularly at Nantes Atlantique Airport, where I have discovered a strong interest in the airport environment ✈︎.
