Microsoft 365 Architect · Fully remote (UTC+7)
Jean-Baptiste Erceau
Twenty years of Microsoft environments, from SharePoint 2007
to Copilot. I help organisations whose tenant was built layer upon layer
to clean up their permissions, get ready for Copilot and migrate without
losing data.
Available from March 2027, when my current engagement ends.

Microsoft 365, at scale
Currently engaged at the FPS Finance (Belgian federal
Ministry of Finance, Brussels): governance of a Microsoft 365
E5 + EMS E5 tenant with 23,000 identities, 35,000 mail recipients
and more than 2,000 Teams. Based in Thailand, my day starts before
yours: overnight incidents are analysed before your first
coffee.

First career
Blackball billiards
French #1 for three seasons (1998-2001) and
European Team Champion in 1999. A first life as a
professional competitor, documented by the press of the day, back when
results were printed in newspapers, not posted online.

What connects them
One and the same discipline
Competitive billiards trained me, from a young age, in exactly what my
job demands today: reading a critical situation, weighing every possible
path and its margin for error, choosing the winning sequence, then
executing it cleanly, under pressure, with no practice shot. Migrating
4,000 mailboxes with zero downtime is the same game: it is won in the
preparation.
