About Olivier

After a long professional break in 2025 (sabbatical year) for house renovation, I am immediately available for a new mission.

Freelancer since 2010, I support large companies and ETIs in structuring, quality, and valuing their data (MDM, PIM, migration, data quality). Data has been the common thread throughout my career for 25 years. I also act as a project manager for complex multi-SI and multi-stakeholder projects, with a good ability to bridge the gap between business needs and technical constraints.

My career in a few words: after a university degree in geography (specializing in geopolitics, then a DESS in geographic information systems), my career turned towards IT (through geomarketing), information systems, and project management. I now have over 25 years of experience. With a strong taste for data quality and reliability issues.
