What I'm looking for

I’m looking to solve real business problems through pragmatic Microsoft 365 and Low-Code solutions, working with trusted teams that value honest collaboration, secure governance, and meaningful digital adoption.

At Squaremiled and PwC Luxembourg, I advise users and IT teams on Microsoft 365 strategy, implement complex Low-Code solutions, define governance, and lead adoption through evangelization and training. I also lead pre-sales activities and prepare offers grounded in client needs.

Over two decades, I’ve moved organizations across industrial, IT, telecom, finance, and public-sector environments from legacy processes to scalable digital workflows. My work spans SharePoint migrations and intranets at ArcelorMittal, collaboration solutions for the European Commission, and Microsoft 365, Power Platform, and automation architecture across Luxembourg clients.
