Tell me more about the metrics you work with.

In working with the product, I use different metrics depending on the goals:

• Engagement metrics: DAU/MAU (daily/monthly active users), session duration, viewing depth.
• Conversion metrics: percentage of users who performed a target action (purchase, registration).
• Retention metrics: retention rates on the 1st, 7th, 30th days.
• Product performance metrics: load time, errors, stability.
• Growth metrics: number of new users, churn rate.

For example, for a mobile app, it is important to track DAU to understand activity, and retention rate to assess loyalty. For e-commerce — conversion and average check.

I use analytics tools (Google Analytics, Mixpanel, Amplitude) for data collection and visualization, which helps in making informed decisions for product development.
