About

A Swiss-certified IT technician (CFC), I learned the job on L1 support backing up L2 at BCV, Hôpital Riviera-Chablais and Gétaz-Miauton: incident diagnosis, tickets, Active Directory / Azure AD accounts and access, Microsoft 365, Windows 11 and Teams migration, workstation deployment.

Outside work I run my own Linux servers and a home automation setup my family relies on every day. That is where I practise what day-to-day support demands: find the root cause instead of the workaround, measure before fixing, back up and document.

I use AI every day, in a controlled way: assistants such as Claude and Codex to document, write scripts and speed up troubleshooting, and AI agents built into my n8n workflows. Always with human review, and never with sensitive data in prompts.

I was also a team leader (sergeant) in the Swiss Army signal troops from June 2025 to May 2026: leading a team, staying reliable and communicating clearly under pressure.

Projects

Each project has its own technical write-up: architecture diagram, configuration excerpts and case studies of real outages I solved. Write-ups are in French.
