Sergo Medin

Profile

I lead a team of 7 analysts at Avito, focusing on sales analytics for the real estate vertical. I’m currently driving the implementation of a strategy I developed for the team, with a strong focus on measurable business impact — from streamlining reporting processes and introducing modern BI approaches to fostering a data-driven culture. I actively share my expertise both internally and externally. I publish articles on major industry platforms, speak at professional meetups, and run internal training sessions. Previously, I worked on monetization, user acquisition, and retention analytics at Yandex, as well as on mobile product development.
