About Sébastien

Freelance IT consultant specializing in Android mobility and MDM solutions (SOTI MobiControl, Microsoft Intune), I work on projects, audits, and expert support missions, primarily remotely, for multi-site environments.

I assist companies in implementing, migrating, and optimizing Android mobile fleets, as well as resolving complex IT issues related to mobility.

With over 15 years of experience in demanding professional environments (retail, logistics, field), I undertake high-value-added missions such as:

• Deployment and administration of MDM solutions,
• Management and security of Android fleets,
• Advanced IT support (N2/N3),
• IT project support (deployments, migrations, equipment changes),
• Audit and structuring of mobility usage.

Accustomed to working remotely as well as for occasional on-site interventions, I am recognized for my autonomy, rigor, and ability to manage a project or technical issue from end to end, in collaboration with internal teams and service providers.

I primarily work on projects, audits, or technical support missions, with clear communication and a constant objective: to deliver a reliable, clean, and operational solution.
