In my previous role, I built a consolidated Power BI reporting landscape for digital and offline media, integrating over 10 external data sources. My focus was on continuous improvement and maintenance of existing data models, as well as creating high-performance Microsoft Power BI reports.

I managed central ETL processes and developed reporting solutions for over 30 different data sources, utilizing modern technologies such as Python and Google BigQuery. Simultaneously, I implemented automated data upload flows into the Google Cloud Platform and made data-driven processes more efficient.

A significant part of my work involved data-based consulting and interpreting insights for internal and external stakeholders. To promote data-driven decisions within the company, I conducted training sessions and onboarding, covering topics such as Data Visualization, ETL processes, and Power BI.
