About
A foundation in statistics.
Practical experience.
I'm Eyüp. I studied statistics at Selçuk University. I began working as a freelance data analyst during my studies, analysing datasets from different sectors.
My work has covered every stage, from preparing data and choosing an appropriate analytical method to visualising and reporting findings. I value results that are clear, understandable and useful for decision-making.
Since December 2025, I have worked at Çelikler Holding as an Assistant Specialist in Fleet and Fuel Monitoring.
