About Vanuel

Consultant in data management, data analytics, data governance and applied AI, I support organizations in structuring their data assets and transforming them into concrete solutions with high business value.

I intervene on three complementary dimensions.

The first is data structuring: business process modeling, data object formalization, workshop facilitation, data owner training, glossary, catalog, quality rules, and governance frameworks.

The second is data analytics: data analysis, indicator production, reporting, business restitution, decision support, and making useful information visible for steering.

The third is the implementation of data and AI solutions: prototypes, MVPs, business dashboards, local data platforms, assistants, business applications, or solutions combining data, product, and automation.

My positioning is that of a profile capable of bridging the gap between business, governance, analytics, and execution. I can therefore be involved in framing and structuring a data subject, as well as in producing analyses, designing a useful tool, or contributing to a more innovative AI-oriented solution.

We were very satisfied with Vanuel's work, as he successfully took over a VBA program for 500 people as an emergency, optimized it, enriched it with multiple KPIs, and integrated them into PowerPoint in an automated graphical format. Vanuel quickly understands needs and delivers quality results. His code is documented and well-structured. I recommend him.
