I’m an experienced Business Intelligence Analyst specializing in end-to-end data solutions. My expertise spans the entire data life cycle - from setting up servers and databases, through data extraction, transformation, and modeling, to building insightful reports and visualizations. In addition to my BI work, I also provide freelance services in web scraping, data transformation, API integration, and web application development.
DB Cargo PolandAt DB Cargo, I am responsible for extracting data from various systems, including several legacy platforms that require special attention when automating data extraction processes. I transform this data using technologies such as Tableau Prep and Python (with libraries like Pandas and PySpark).
A key part of my role involves delivering insights to the executive board by generating reports on critical KPIs—such as the volume of cargo transported over specific periods, total kilometers covered by our locomotives, and the monthly working hours of our locomotive drivers and railway auditors.
I'm also responsible for developing an application that generates work schedules for over 600 employees involved in railway operations. In addition, I assist with setting up SharePoint spaces and contribute to internal tool development through Power Automate and Power Apps integration.
PwC Service Delivery CenterI was a part of an international technology team focused on migrating global clients to a new data architecture. I was responsible for setting up environments and building workflows to upload and parse transactional data, using tools such as Groovy, Google Workspace, VBA, and Alteryx.
ALDI PolandI was an apprentice in the Category Management Department at Aldi, where I used VBA and Power BI to identify missing records and ensure accurate data entry into the SAP system. I also contributed to creating planograms—visual layouts that determine optimal product placement in stores to maximize efficiency and sales.

Outside of work, I find joy in spending time in nature. My favorite activities include running, hiking in the mountains, and taking long walks with my dog Fokus—often with an ice cream in hand.
When I’m indoors, I like tinkering with my self-hosted server, writing scripts for home automation, and building web scrapers for fun and experimentation. I’m always curious about how things work and enjoy exploring new ways to automate the world around me.
