I am a Senior BI and Business Analyst with more than 20 years of business operations experience and over five years of end-to-end BI and data warehouse delivery experience. I translate business needs into technical requirements, data models, ETL specifications, and validated dashboards that support strategic decision-making.
I specialize in advanced SQL, dimensional and star-schema data modelling, data warehouses, lakehouse environments, and Power BI. As a Microsoft PL-300 certified Power BI Data Analyst, I build semantic models, DAX measures, Power Query transformations, DirectQuery reporting, and optimized self-service dashboards.
I work closely with business stakeholders, IT teams, data engineers, architects, and data scientists throughout the product lifecycle. I lead requirement-discovery sessions, identify dependencies and blockers, convert ambiguous requests into measurable KPIs and backlog items, and deliver in Agile environments.
My recent work includes rebuilding multi-country revenue and utilization models, designing SQL transformation layers and analytical warehouses, integrating REST APIs and public datasets, and creating geospatial and financial analytics models. I have supported leadership teams with live, reconciled reporting for operations, finance, investment, and market-entry decisions.
I also use AI-enabled tools such as Claude, ChatGPT, Microsoft Copilot, and Make to accelerate data preparation, modelling, automation, and reporting while critically validating all outputs. I am a Polish national based in Italy, fluent in English, and available immediately for remote roles across EMEA.
