About Sami

System & Network Administrator – 8 years of expertise in demanding environments
(Food Industry, Medical, Real Estate)

Your daily challenges, my concrete solutions:
Are you spending hours on repetitive manual tasks? Are your shared mailboxes poorly configured, and your Microsoft 365 tenant looks like a permanent construction site? I help you save time, reduce costs, and simplify the management of your infrastructure.

What I solve for you:
- Automation of time-consuming processes:
Bulk user creation/deletion via custom PowerShell scripts (integration with AD/Entra ID).
Automatic cleanup of inactive or obsolete accounts.
Result: Up to 50 hours/month saved for your teams.
- Optimized and managed Microsoft 365 Tenant:
Clean migrations (Exchange, Teams, SharePoint) without residue or disruption.
License management: Removal of duplicates and optimal allocation to reduce costs.
Configuration of shared mailboxes and collaborative access (Teams, SharePoint).
- Maintenance and scalability:
Clear documentation to facilitate onboarding and internal audits.

Why work with me?

Field experience: 8 years solving complex problems.
Pragmatic approach: I focus on actions with immediate impact (e.g., AD workflow automation, O365 environment cleanup).

Flexibility: One-off missions (migration, optimization) or monthly maintenance contracts for a consistently performing infrastructure.

My priority missions:
- Automation via PowerShell: Bulk user creation, AD cleanup, custom reporting.
- Optimization: O365 Tenant, Entra ID (Azure AD), Exchange, Teams.
- Maintenance contracts: Monitoring, updates, and continuous adjustments.
