My name is Mariia, and I’m a data analyst focused on turning data into meaningful insights that explain not just what happens, but why.
My relationship with data began when I joined a company with a strong data-driven culture, where most decisions were based on data. That’s when I realized data is more than just numbers — it can tell stories, describe behavior, and reveal insights that help people make better decisions.
I’ve worked with data across aviation, retail, insurance, and telecommunications, using Tableau and Power BI to turn numbers into clear, actionable stories that support real business decisions.
I hold a degree in Automation of Computer-Integrated Technologies and have also spent several years in the education sector, where I worked in customer support, marketing, and project management. Across all roles, I relied on data to guide decisions, track results, and measure impact — which showed me that data can be dynamic, human, and creative.
Outside of work, I enjoy photography, walking, and discovering new places.
