About Jeremy

Cloud Architect & Outsourced IT Manager – Microsoft 365 & Google Workspace Migration Specialist

Are you preparing for a migration to Microsoft 365 or Google Workspace?
Has your current environment become complex, unstable, or poorly documented?

✅ For nearly 10 years, I have been supporting SMEs in their IT system migration, structuring, and security projects.
✅ I often intervene in high-stakes contexts: rapid growth, mergers, reorganizations, collaborative tool changes.

+1200 users migrated to Microsoft 365 & Google Workspace
+30 migration projects managed end-to-end
No data loss observed
Migrations performed without critical interruption

🚀 I mainly work on:
  • Migration to Microsoft 365 or Google Workspace
  • Tenant-to-tenant migration (mergers, divestitures, reorganizations)
  • Collaborative architecture redesign
  • Implementation of backup and disaster recovery strategies
  • Access security (MFA, identity management, security policies)
  • Structuring of heterogeneous cloud environments
My added value: a methodical, documented, and risk-oriented approach, designed to avoid unpleasant surprises.

🔎 Each project follows a clear methodology:
  • Detailed audit of the existing system
  • Risk identification and development of a migration plan
  • Technical management and stakeholder coordination
  • User support and training
  • Post-migration stabilization and documentation
I don't just focus on technical execution: I provide a global vision to ensure a controlled, documented, and sustainable transition.

Usual deliverables:
– Infrastructure audit
– Detailed migration plan
– Technical documentation
– Security procedures
– Post-migration startup support
I can also act as an outsourced IT referent to ensure the continuity and evolution of your environment after migration.
