About Gérald

Data Consultant – Strategy & Decision Support

Tableau Desktop & Server Certified, I have completed over 20 Data Visualization missions for major players (industry, retail, energy, banking, healthcare, higher education).

Today, my positioning goes beyond simple data visualization.

My goal: to design real decision support systems, focused on business performance and strategic impact.

🎯 My Approach

I don't just assist with dashboard creation.
I intervene on:

● Clarifying business challenges
● Structuring truly decision-making indicators
● Performance-oriented data modeling
● Transforming reporting into a strategic arbitration tool

Each project aims to answer a simple question:
► What decisions will be made thanks to this data? ◄

🧩 Areas of Intervention

● Proof of Concept & strategic framing
● Tableau Architecture & administration
● Analytical application design
● Data source structuring
● Audit & optimization of existing environments
● Training (Desktop, Server, Prep – from beginner to expert level)
● Coaching & supporting data teams
