About me

💡 Are you looking for a partner who not only understands data, but can translate it into concrete business decisions?

Since 2018, I've been helping organizations better leverage their data. I specialize in BI Consulting and ETL process design in Azure and Python. Combining my technical and business expertise, I help companies automate reporting, integrate various data sources, and reduce the risk of errors.

My approach is simple: before creating code or a dashboard in Power BI,I first understand the business context and real needs. This ensures that the solutions I implement not only work technically but also actually increase the organization's efficiency.

  • BI Implementation – ETL process implementations, data integrations, and report and dashboard design in Power BI.
