Network & Security Engineer Apprentice • Paris, France

Passionate about building secure, scalable infrastructure. Currently pursuing a Master's in Secure IT Project Management while working as an apprentice engineer.

About

Background and approach to IT infrastructure.

I'm a Network & Security Engineer with 3+ years of hands-on experience in enterprise IT environments. My journey started with hardware repair, evolved through network administration, and now focuses on security architecture and automation.

I believe in building infrastructure that's not just functional, but secure by design. Every firewall rule, every VLAN, every script I write is crafted with security and maintainability in mind.
