About Samuel

I quickly resolve daily IT issues in small and medium-sized businesses (Google Workspace, Jira, Slack, access, support organization).

With over 15 years of experience in IT Operations, support, and management, I intervene directly where blockages occur: recurring incidents, misconfigured tools, wasted time for teams, lack of structure.

👉 Specifically, I can help you to:

  • Resolve user problems (access, emails, Drive, permissions...)
  • Clean up and organize Google Workspace / Jira / Slack
  • Structure or upgrade IT support (processes, tickets, prioritization)
  • Implement simple automations to save time
  • Manage specific needs (IT relocation, onboarding, tool implementation)

I prioritize rapid interventions (a few hours to a few days) with immediate impact.

My goal: to save you time, reduce friction, and restore fluidity to your tools.

Available evenings and weekends for specific missions.
