Description

BI consultant specializing in Power BI, SQL, and reporting automation.

I help companies leverage their data to improve business management and decision-making.

My interventions include:

• Power BI dashboard creation

• Excel and Power BI reporting automation

• Data analysis and KPI monitoring

• Data transformation and preparation (SQL, Power Query)

• Performance analysis and decision support

With 6 years of experience in IT and operational environments, I have developed a dual expertise in data analysis and performance management. In my last role, I helped reduce data processing time by 70% through reporting automation.

My goal is simple: transform data into clear and actionable indicators to help teams save time and make better decisions.
