Description

Data Analyst passionate about the clarity that good data can reveal, I support companies in their analysis, automation, and visualization needs.

With a Master's degree in Data Analytics and several experiences, I have learned to transform raw files into simple and actionable decision-making tools.

What I do:

• Creation of clear and narrative Power BI dashboards

• Automation of files and processes (Python, SQL, Advanced Excel, Power Query, VBA)

• Data analysis and recommendations

• Structuring and cleaning databases

I enjoy understanding business needs, digging into data, and translating it all into visuals that speak immediately. Always open to fluid exchanges and a clear framework, I adapt quickly to my clients' environments and communication styles.
