During my time as a Product Data Analyst at XYZ Company, I conducted a comprehensive analysis of product performance data to support product development decisions. One project that exemplifies this is when I was tasked with analyzing customer engagement metrics to identify opportunities for product improvement. I utilized SQL and Python to extract and transform the data, and used Tableau to visualize the findings. Through this analysis, I identified a concerning trend of declining user engagement with a particular feature. To understand the underlying cause, I conducted user surveys and performed A/B testing. The results revealed that the feature had a usability issue, leading to dissatisfaction among users. I presented these findings to the product development team, highlighting the need for improvements. As a result, the team prioritized the redesign of the feature, resulting in a significant increase in user engagement and overall product satisfaction. This experience demonstrates my ability to effectively analyze data, utilize statistical tools, and communicate findings to drive product decisions.
