About

Hi, I'm Evgeny Ivanov, an applied scientist. Currently, I'm a Principal Data Scientist at Profi, a marketplace of services where customers can find professionals and professionals can find customers. At Profi, I've:

• Developed models, solved optimization problems, and led projects that improved key metrics of the two-sided matching platform.
• Created a Data Science team to enhance the core algorithms of the marketplace. I hired machine learning engineers, analysts, and a product manager.
• Designed and analyzed advanced experiments when classic user-based A/B tests were not possible.

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

I also developed a couple of open source Python packages:

• tea-tasting is a Python package for the statistical analysis of A/B tests.
• rico is a Python package for creating HTML documents from rich content: dataframes, plots, images, markdown, etc.

My interests include:

• Solving optimization problems using machine learning and maths.
• Two-sided matching platforms, marketplaces, and economics.
• Statistics and causal inference.
• Python and software engineering.
• Decision making and management.
