About

I'm Evgeny Ivanov, Head of Product Analytics at Yandex Search. Previously, I was a product director and principal data scientist at Profi, a services marketplace with 21K services and 19M customers. Before joining Profi, I built a demand forecasting and inventory optimization system for a fashion retail chain.

I also created tea-tasting, the most-starred Python package for the statistical analysis of A/B tests.

This blog is where I share insights on the topics I work on and care about, including data science, decision making, economics, and management.
