I build SQL and Power BI analytics that help product teams make self-service decisions.
Russian FederationWhat I'm looking for
I'm building a portfolio of product, communications, and fintech analytics projects using SQL, Power BI, Python, and forecasting models.
In an e-commerce and retail analytics project, I analyzed data with SQL joins, aggregations, and window functions, then built an interactive Power BI dashboard with DAX metrics so teams could track performance without requesting analyst reports.
For Bakken production forecasting, I designed a SQLite database from 899 rows of PDF reports and EIA data, built SARIMA and XGBoost forecasts, and improved RMSE by approximately 28% after identifying and fixing data leakage.
I'm an Economics student at Mari State University who enjoys translating business problems into structured analytical models, from raw data through forecasting and visualization.
