Tell about your experience working with data and what tasks you performed.

In my work with data, I was involved in collecting, processing, and analyzing large volumes of information to support product decisions. The main tasks included:

• Preparing and cleaning data from various sources (databases, APIs, logs).
• Conducting cohort analysis and user segmentation to identify behavioral patterns.
• Creating dashboards and reports to monitor key product metrics.
• Formulating hypotheses and conducting A/B tests to evaluate the impact of changes.

For example, I analyzed user activity data to identify reasons for churn and suggested interface improvements, which helped increase retention by 10%.
