Freelancer profile translated to English.

Description

You have data everywhere — CRM, Google Analytics, Excel files, ERP, marketing tools, but you don't really know what they're telling you?

I transform your raw data into clear and actionable Dashboards that show you concretely:

- Which levers are driving your growth (and which are dragging down your margins)

- Which acquisition channels are truly profitable

- Where your hidden growth opportunities lie

My approach is different: with a dual background in Digital Marketing (Master's degree) and Data Analytics (Le Wagon), I don't just crunch numbers. I ask the right business questions and deliver concrete recommendations to make better decisions.

I work with SMEs, startups, and e-commerce businesses that want to structure their data to manage their business with clarity.

My technical stack:

- Collection & storage: BigQuery, Fivetran

- Transformation: SQL, dbt

- Visualization: Power BI, Looker Studio

- Analysis: Advanced Excel, Python

- Automation: n8n

What I deliver: turnkey, documented Dashboards designed for you to use independently.
