Tomek Jamiński is the Head of Data Science at OLX Group, where he leads work spanning data science, business intelligence, and research. A self-described data native and servant leader, he is fluent in both the ecommerce and FMCG domains, and this dual fluency lets him understand the mechanics and cultures of both worlds when making data-driven decisions.

Tomek loves taking on challenges that connect data and business. He is passionate about building cross-functional teams, enjoys working with critically thinking leaders, and focuses on developing the strengths of every person on his team. His leadership approach is grounded in formal training: he holds an MSc in Electronics and Telecommunications from the Poznań University of Technology and a postgraduate degree in Corporate Management from the Poznań University of Economics, a combination that bridges deep technical understanding with business management.

Outside of work, Tomek is a husband and father for whom family comes first. In his free time he enjoys aikido and music.
