About Sarah

Are you using Microsoft 365, but know your organization is only scratching the surface of its potential? Do your teams waste time on manual tasks, your files are scattered, and nobody is sure if your tenant is properly secured? That's exactly where I come in.

I am a Microsoft 365 and Power Platform consultant based in Geneva. I help SMEs, associations, and organizations in French-speaking Switzerland transform their Microsoft 365 environment into a truly efficient and secure work tool.

What I deliver concretely:

Custom business applications with Power Apps: inventory management, internal request forms, equipment logs, project tracking. Apps connected to your SharePoint or Excel data, ready to use in 5 to 10 days.

Process automation with Power Automate: approval workflows, conditional notifications, document routing, system synchronization. Stop wasting time on manual follow-ups and validations.

Microsoft 365 audit and security: comprehensive review of your tenant, MFA verification, license policy, external sharing, inactive accounts. You receive a clear report with priority actions.

SharePoint Intranet and document management: site architecture, library structuring, migration from Google Drive or file servers.

Training and awareness: practical sessions on cybersecurity, SharePoint, or getting started with your new applications.

What sets me apart: I don't sell theoretical advice. I build and I deliver. Every engagement results in an operational deliverable that your teams use the very next day. My experience in international organizations allows me to adapt quickly to multicultural and multilingual environments.

Available for fixed-price or time-and-materials engagements, remotely or on-site in French-speaking Switzerland.
