About Erwin

Since November 2023, I am back with the CAGIP SQL Server BUILD DBA team for the administration of the ever-growing park. From November 2022 to October 2023, at GENERALI, I carried out the migration of the obsolete park with skills transfer to the offshore team in India. From 2015 to 2022, I was the reference in France for CAGIP for an offshore DBA team in India for the operation of the large park of SQL Server servers. In 2020, I moved to the BUILD team. My activity included in particular the management of obsolescence projects.
I also have extensive experience in the design and modeling of transactional and decision-support databases, particularly for major players in the tourism industry: Transat France, Expedia, NG Travel, Look-Voyages, Directours.
My database experience began with the design and development of management software for institutional investors (Sybase, SQL Server, and Oracle), still distributed by the company Hexalog, which I founded in 1986.
For 20 years, I have been providing expertise in MS SQL Server.
I am often called upon at the beginning of projects for architecture, modeling of transactional databases, Data Warehousing, and Business Intelligence.
I also provide consulting for development teams and support for administration, often on transactional systems operating 24/7.
My assignments have led me to design transactional databases for major players in Tourism and E-Commerce.
The software I designed has led me to develop strong functional expertise in accounting, management, and other peripheral functions (payroll, management control, various analyses).
