I'm İrem, a Data Analyst who transforms complex datasets into clear, actionable insights that drive real business results.
Available for freelance work
I'm a data analyst with hands-on experience in customer behavior, sales performance, and business intelligence. I believe that behind every dataset, there's a story waiting to be told—one that can shape better business decisions.
My toolkit: Python, SQL, Tableau, and Power BI. My strength is translating raw numbers into narratives that drive action and deliver measurable results.
I see analysis as the process of bringing together all the pieces of a business problem and turning them into a clear picture. I don't just crunch numbers—I ask the right questions and search for answers to explore the "why" behind the data.
From building predictive models to designing interactive dashboards, my goal is to make data accessible and actionable for teams at every level.
