PROJECT EXPERIENCE
Project topic: Assessing user retention rates using Google Sheets and SQL based on cohort analysis
Assessing user retention rates using Google Sheets and SQL based on cohort analysis
Tools: SQL, Google Sheets
My tasks: Cleaning and transforming dates in various formats using SQL, calculating user cohorts and their tenure with
the company, building interactive cohort tables in Google Sheets, analysing user retention rates for different
acquisition sources, and comparing the behaviour of promotional users and organic users.
Result: Promotions work well for attracting lots of people at once, but these people don’t become regular customers.
We need to think about how to retain «promotional» users, or invest more in attracting «organic» customers.

applying descriptive statistics and data aggregation methods, analysing measures of central tendency and percentage
distributions, grouping and filtering data according to various criteria, handling missing values and outliers, and
visualising analysis results in a user-friendly tabular format.
Result: Big data analysis in the film industry. I implemented the full data processing cycle (ETL): from loading raw files
to drawing analytical conclusions. Demonstrated the ability to identify hidden patterns in the data (for example, the
rapid decline of the Silent genre in the 1920s) and presented them in graphical form.
