Helping companies simplify with data
Hi! I’m Anna, a data visualization expert based in Basel, Switzerland. I help companies simplify processes to save time and money.
Having lived in Poland, Canada, Italy, Germany, and now Switzerland, I have a background in linguistics and digital marketing with branding, and I’m a certified business analyst and data scientist.
My experience ranges from branding in Poland, through supply chain and finance in Germany, to big pharma, biotech, and medtech in Switzerland. Since July 2025, I have been supporting the data analysis and storytelling for Roche’s Global S&OP, designing executive-level visuals and insights that help demand planning across global pharma markets.
