About Marina

📊 Data Analyst specialized in Power BI, SQL, and Data Storytelling
You have data. Lots of data. Maybe even too much. My role? To transform it into clear, useful, and actionable insights for better decision-making.

For over 2 years, I've been assisting Finance, Sales, Product, and Tech teams in creating Power BI dashboards, analyzing data, and improving data quality. I've worked in various environments such as Edenred, Société Générale, SNCF, and Paris Habitat.

Specifically, I can help you to:
✔ Build intuitive Power BI dashboards
✔ Create relevant KPIs for your business
✔ Clean, structure, and validate your data
✔ Automate your reporting
✔ Make your data speak without needing a 300-page dictionary

My favorite tools: Power BI, SQL, Python, Databricks, PySpark.

What my colleagues appreciate most? My ability to bridge the gap between business and technical teams, while maintaining a pragmatic and results-oriented approach.

And because a dashboard is only useful if it's used, I pay special attention to the user experience and the adoption of the solutions I develop.

🚀 Need a dashboard, an analysis, or simply to bring some order to your data? Let's talk.
