About

Hi, I'm Evgeny Ivanov, a product director and former principal data scientist at a services marketplace where customers and professionals can connect. As a product director:

• Reorganized teams, redefined objectives, and hired an analytics manager.
• Introduced company-wide practices to streamline critical decision-making in projects and to enable the emergence of cross-team initiatives with greater impact.
• Initiated and oversaw several projects, including one that increased revenue in one of the largest categories by 7%.

Previously, as a principal data scientist:

• Formed a data science team to enhance the core algorithms of the marketplace and hired machine learning engineers, analysts, and a product manager.
• Developed models, solved optimization problems, and led projects that improved key metrics of the two-sided matching platform.
• Designed and analyzed advanced experiments for cases where classic user-based A/B tests would not be valid.

Prior to that, I developed and implemented a demand forecasting and inventory optimization system for a fashion retail chain.

I also developed tea-tasting—the #1 Python package for the statistical analysis of A/B tests, as measured by the number of GitHub stars.
