Jean-François Coroller

IT & Data Consultant, I support SMEs and growing teams in structuring their tools, automating their processes, and leveraging their data to better manage their business.

As an Information System Manager in e-commerce, I design simple, robust, and maintainable solutions, always starting with business needs before tools.

🔧 What I implement

• Reliable business applications and repositories (Airtable)

• Automations between tools to eliminate manual tasks (Make)

• Data centralization and validation (Airbyte / Fivetran / BigQuery)

• Clear and decision-oriented Power BI dashboards (sales, finance, operations)

🎯 My goal

To save you time, validate your data, and give you a clear vision to make faster and better decisions.

🤝 My difference

• Dual field + technical expertise

• End-to-end vision (process → data → management)

• Clear, educational communication without unnecessary jargon

📅 Available for one-off missions (audit, co-construction) or complete projects.
