Tell me about a specific project you worked on.

In one of my projects, I analyzed user behavior on an e-commerce website. The goal was to identify the reasons for a decrease in conversion in a specific customer segment.

Main steps:

• Collecting and cleaning data from various sources: web server logs, CRM, transaction data.
• Building a sales funnel and analyzing dropout points.
• Clustering users based on behavior and demographic data.
• Identifying patterns related to purchase refusals.

As a result, I proposed changes to the interface and marketing strategy, which increased conversion by 15%. I used Tableau for visualization and Python (pandas, scikit-learn) for analysis.
