About Vincent

First a Java developer (after being a Lego architect for a long time ;)), I have focused for the past 6 years on massive data analysis (the famous BIG DATA!).

I love digging into data (analysis), making it speak for itself (machine learning), and using the results to offer ever more value to clients/users!

I have already had the opportunity to work in several fields (banking / telecom / large retail / institutions), but data analysis applies to all organizations, large or small.

What I can offer you (almost exhaustive list):
✓ Audit of your data (volume / quality / completeness) and your use-cases
✓ Recommendation of technical architecture (big data solution or other / data flows)
✓ Installation and deployment of this architecture (I can work with Ops teams to assist them)
✓ Assistance with functional architecture (primary sources / transformations / downstream needs)
✓ Implementation of a BI / reporting / dashboarding solution (experience with Tableau and BIRT)
✓ Definition and analysis of needs with the relevant functional teams (marketing / technical / management control...)
✓ Development of data loading / transformation / analysis workflows
✓ Data analysis and organization of "demos"
✓ Proposals around machine learning (Random Forest / K-means / DBScan...)
✓ Training of teams on the technical and functional aspects of the data approach
✓ Internal recruitment for your teams so that you can maintain control over your data and its exploitation

Looking forward to working together!
