About Sara

Data engineer with 8 years of experience, I work on the design of data pipelines, the integration of multiple sources, and the creation of Power BI dashboards, in demanding environments such as industry, analytical sciences, or distribution.
I strive to understand business challenges before proposing solutions, to deliver something useful and maintainable in the long term.

What I concretely work on:

- Design and implementation of data pipelines (ETL, Data Vault, Azure cloud)
- Modeling and integration of multiple sources (SQL, Python, MongoDB)
- Creation of high-performance Power BI reports and interactive dashboards
- Technical leadership of Data teams and Agile/Scrum piloting

I am actively interested in no-code automation (Make, n8n, Airtable) and exploring how these tools can complement existing data solutions.
