About Sébastien

Transformation & Operational Governance Architect – Infra / AD / M365 – 22 years Exp

IT governance & infra expert with 22 years of field experience: 16 years technical (Windows, Exchange, network, storage, MDM, virtualization, cloud migration, PowerShell) + 6 years strategic management (Service Manager, Project Manager, SDM, director).

I transform problem systems into living systems: - Audit, restructuring, master plan, AD/M365 migration, hardening, Zero Trust – never a downtime. - Real governance: KPI / SLA / SLO / SLI definition, targeted automation, Kanban, Confluence, knowledge bases – autonomous teams in 6 months. - Transition in/out: recovery of third-party projects, complete handover, skills transfer – 0 loss of value. - Recruitment, roles, RACI, committees: I structure people as much as technology. - Needs analysis: I translate a CIO's "I have a problem" into a signed roadmap, without the BS.

Immediate availability – Bordeaux + occasional travel – full remote accepted Daily rate: €950 (negotiable based on duration/stakes) Contact me: let's look at your mess, fix it, and get you back on track.
