About Quentin

Available for your freelance missions as well as for the overall support of your IT infrastructure.

Originally from Savoie, I founded Gypatech to support companies in Savoie and Haute-Savoie in managing and evolving their IT infrastructure. My role is to be your single technical point of contact to ensure a stable and secure work tool.

Background & Commitment:
My expertise was built over several years in an IT consulting firm in Annecy, followed by a position as a Modern Workplace Engineer in New York within Business France.

This experience allowed me to confront the practical needs on the ground with the requirements of managing critical international IT infrastructures. Today, I put this dual technical culture at the service of local organizations.

Technical & Field Expertise:
  • Networks & Wi-Fi: Audit, design, and physical installation (cable laying, RJ45 cabling, patch panel configuration) on Fortinet, Ubiquiti, and Meraki technologies.
  • IP Telephony: Migration, configuration, and maintenance of VoIP solutions (Yeastar, 3CX).
  • Modern Workplace: Administration of Microsoft 365 tenants (Azure, Intune, Defender) and access security.
  • Cybersecurity & Backup: Stormshield (CSNE) and Cisco expert. Implementation of protection strategies and backup plans (Veeam).
