At Yandex Practicum, I’ve analyzed marketplace activity, conversion, retention, and revenue using order, event, and marketing cost data. I built cohort analyses and visualizations to assess customer behavior and business performance.
For a delivery app project, I analyzed the customer journey and identified a major drop-off at mobile phone verification. I also applied RFM segmentation and proposed customer reactivation and loyalty initiatives.
In a fintech onboarding A/B test, I evaluated conversion and deposit metrics using statistical hypothesis testing, distinguishing significant improvements from inconclusive results.
I’ve also used SQL and PostgreSQL to extract, filter, join, and aggregate data, and created dashboards in Yandex DataLens. I’m developing my data analysis skills through Yandex Practicum and hold a bachelor’s degree in Management from Russian-Armenian University.
