French independent SQL server expert, with 25 years experience. An old-fashioned relational database fan, open to NoSQL wanderings, but without ORM, please. More geared towards database development than administration, but needing to act as a DBA most of the time. He has authored several books, about SQL Server optimization, SQL Server security, and NoSQL. He has also authored two video trainings at Pluralsight, and many video trainings in French at Linkedin Learning, and spoke at many community events across Europe. He could have been a cook, a writer or a mountain guide. What does he do in the database business ?
