About Stéphane

Specialized in the Microsoft 365 ecosystem and technical leader of my team, I design advanced automation solutions based on PowerShell 7.x, intensive use of Microsoft Graph, and a fully object-oriented architecture.

I have developed my own Scripting Factory, a modular framework using design patterns, designed to:
• automate massive tasks in Azure, M365, SharePoint, Intune, and Exchange,
• properly structure scripts through classes and strict conventions,
• automatically generate reusable scripts using AI.

I also work on tenant-to-tenant data migrations for carve-in and carve-out scenarios, with automated tools to manage calendars, mailboxes, groups, SharePoint, permissions, and complex inter-service dependencies.

On the AI side, I am training GitHub Copilot to understand my framework and patterns to automate script generation and industrialize production.

My Goal: accelerate development, standardize practices, and reduce human errors in large M365 environments.

I am also industrializing my framework to make it scalable:
• containerization via Docker,
• parallel execution in Kubernetes,
• optimization of cache, MSAL connection pooling, and Graph API quota management.

To orchestrate complex pipelines, I use n8n: triggers, API integrations, data synchronization, and workflow triggering in Kubernetes.
For observability, I use Grafana to monitor logs, load, and API calls.
