PROFILE / CÉDRIC BARME
One single contact,
14 years on the field.
NSY is a one-name practice. Behind every mission, one person — me — with 14 years spent in the technical engine rooms of France's largest financial institutions.
I have designed, delivered and debugged critical systems used by millions of people every day — often without their knowing. I have seen what works, what breaks, and what fails to live up to the sales promise. That experience is now serving a limited number of clients — by design.

Working principles
- No pyramid. No hidden junior behind my name, no commercial layer. The person who pitches the mission is the one who delivers it — from scoping to production.
- Technical honesty. I say when a project is the wrong idea. Better to lose a mission than a client.
- Three clients maximum. To stay truly available and keep a non-negotiable quality bar.
