Description

I help companies turn their data into useful information for decision-making, eliminating manual processes and improving efficiency.

I specialize in data engineering, automation, and Business Intelligence, working primarily with SQL, Python, Power BI, and cloud environments (Azure Data Factory, Azure SQL, Blob Storage).

I bring value to projects where:

Data is scattered or poorly structured

There is reliance on Excel and manual processes

Reliable and automated reports are needed

Integration of different data sources is required

I handle the entire data lifecycle:

Design and development of ETL pipelines

Process automation with Python

Data modeling and SQL query optimization

Creation of clear, business-oriented Power BI dashboards

What sets me apart is a practical approach: simple, maintainable, and results-oriented solutions, avoiding over-engineering.

I have worked on projects where we have achieved:

Reduction of manual work hours

Improvement in data quality and consistency

Faster decision-making with automated reporting

If you need to transform your data into a real business tool, I can help you.
