Built a revenue forecasting solution in Snowflake to turn historical operational data into a repeatable forward-looking forecast. I prepared and transformed the data in SQL, engineered time-based and business features, tested multiple forecasting approaches, and used walk-forward backtesting plus forecast-vs-actual analysis to evaluate accuracy, bias, and performance over time.
