O mnie

Data Analyst focused on revenue, churn, and product analytics, with hands-on experience in end-to-end analytical projects. I work with Python, SQL, and Power BI to transform raw data into actionable business insights. My projects cover the full workflow — data preparation, metric design, analysis, and executive dashboards. Currently building a portfolio around retention, monetization, and product decision support.
