About Léonard

Data / Analytics Lead with a strong business and product approach, I support companies in structuring their data, analytics, and performance management challenges.

I work at the intersection of business, product, marketing, and technical teams to frame needs, define measurement frameworks, design self-service analytics products, and transform complex topics into truly actionable tools and insights.

During my assignments, I have worked on web analytics, BI, KPI governance, tracking, experimentation, analytics engineering, and decision support issues in international environments with high data volumes.

I have notably led or contributed to:
• Analytics and BI roadmaps
• Building dashboards and self-service data products
• Defining KPIs and measurement frameworks
• Structuring data and analytics governance
• Analytics engineering and data modeling
• CRO, A/B testing, and user journey analysis topics
• Framing and coordination between business and technical teams
• Use cases around AI applied to analytics and data exploration

I primarily work with:
BigQuery, SQL, dbt, Looker Studio, Power BI, Tableau, GA4, Firebase, LookML, AB Tasty, ContentSquare, GTM, Tealium.

I particularly appreciate assignments that require strategic vision, structuring, analytical skills, and a very pragmatic, business-impact-oriented approach.
