In my current role, I generate business reports through end-to-end ETL processes, using SQL to extract and transform data and Tableau to create interactive dashboards.

I use Python for automation and data processing, and I’ve developed SQL-based workflows to consolidate data for business reporting and prepare structured datasets for consistent reporting.

In project work, I’ve created Tableau dashboards for logistics KPIs and applied statistical analysis to historical data, exploring trends and forecasting methods to support operational planning.
