About Svetlana

Hi, I’m Svetlana, a Data Analyst currently working at Dow Jones.

I help businesses make better decisions by transforming complex data into clear, actionable insights. My experience spans SQL, Power BI, Snowflake, Adobe Analytics, Python, dashboard development, KPI design, reporting automation, data validation, product analytics, customer behavior analysis, and stakeholder reporting.

I’m particularly interested in combining traditional analytics with modern AI tools to accelerate data exploration, uncover patterns in large datasets, automate repetitive workflows, and extract insights from unstructured data such as customer feedback and text content.

Whether you need a dashboard, a reporting solution, a deep-dive analysis, data quality investigation, or support turning raw data into business recommendations, I focus on delivering work that is both technically reliable and easy to act upon.
