Your data, turned into decisions.

Hello! My name is Benjamin benjamin vaxelaire.
I work with data end-to-end — from collection to decision — with a real flair for dataviz. Based in Metz, France.
Governance, architecture, BI, visualization: I build clear, accessible tools that teams actually adopt to steer their activity.

My methodology

What are your objectives and what information is needed to achieve them?

What data do your information systems contain to address these questions?


Why visualize your data?

Visual language is intuitive and effective: it simplifies complex problems and reaches a broad audience. Visualization tools are essential to analyze large volumes of information and make data-driven decisions. Their benefits are many: a synthetic view of complex information, intuitive reading and quick understanding. Visualization resonates with your audience and sparks engagement.
