User Support

Provide support for users and business applications. Manage tickets and requests through tools such as GLPI or Odoo.

Security & Monitoring

Monitor services, respond to incidents, apply security patches, and track vulnerabilities across the environment.

Maintain up-to-date technical documentation, procedures, application catalogues (licences, versions, dependencies), and asset inventories.
