I will perform deep analysis of data and transform it for further use. The service includes data cleaning, normalization, transformation, and calculation of necessary metrics. I work with SQL (ClickHouse, PL/SQL, T-SQL), Python, and MongoDB (NoSQL).
This service is ideal for preparing data for visualization in BI tools or creating analytical reports. For example, I can merge data from multiple tables, calculate conversions, eliminate duplicates, or transform data for further analysis.

3. If necessary, provide sample data or templates.
