Portrait d'Alexis Gardet
À propos

A profile built around reliability, security and operational continuity.

I work in environments where downtime has immediate operational impact. My value lies in combining solid Windows infrastructure expertise with hands-on security work, clear coordination, and a strong ability to turn complex requirements into maintainable solutions.

What I bring

Enterprise Windows expertise: SCCM, Intune, Active Directory, GPO, DNS, software deployment and workstation compliance.
Security execution: EDR evaluation and deployment, incident response framework design, SOC coordination, audit remediation and pentest follow-up.
Operational ownership: critical systems support, network troubleshooting, PowerShell automation, lifecycle management and team enablement.

Why Japan

Long-term relocation mindset: I am actively targeting opportunities in Japan, not casual short-term roles.
International contribution: I bring experience from a regulated airport environment with strong security and operational constraints.
Continuous progress: I am improving my Japanese while remaining fully comfortable working in English-speaking teams.
Expérience
