Who am I?

Hello! My name is Christian, I'm a young dynamic and passionate network and system administrator.

I'm actually in apprenticeship at Bedrock Streaming in Lyon. I love working in teams and share knowledge and skills with people. I'm not afraid of the things I don't know yet, open for challenges.

I'm also a photography, music and beer lover.
