Description

Your data exists. Your teams don't read it.

I design Tableau dashboards that your managers understand in 30 seconds and actually use.

Certified Tableau Desktop Specialist & Tableau Consultant.

I am a Tableau Data Visualization consultant. My scope: from defining the need to putting the dashboard into production without getting lost in the technical details.

Development of Tableau reports
Conducting needs assessment workshops
Dashboard wireframing and prototyping
Support for user adoption and change management

For what needs:

You are migrating Excel reports to Tableau
You need a quick dashboard PoC before industrialization
Your users are not adopting the existing BI tools
You are deploying a BI platform and looking for a Tableau referent
You want to standardize reporting across multiple teams
You are changing your ERP or data platform and need to migrate your existing reports

Recent assignments:

OPTEVEN: Creation and/or adaptation then migration and redesign of all Tableau reports following an ERP change, creation of documentation
Action Logement (APAGL): Creation and/or adaptation then migration of Tableau business reports following a data platform change, creation of procedures and user training

SNCF / Digital General Directorate: Creation & migration of reports, upskilling of junior teams.
BNP Paribas IRB: 2 complete reports for the COMEX for countries outside the EU (RETAIL & SME branches), Alteryx & Tableau

I work from the end-user perspective: I speak the language of managers, not just developers.

My approach: workshop -> mockup -> PoC -> production deployment -> adoption.

Send me your needs, I will respond within 24 hours.
