Senior🎓
Top SchoolPolina Yershova is a Product Owner with 11 years in IT and digital projects, combining hands-on analytics training with practical product delivery experience. She has led cross-functional teams and launched multiple systems from scratch—most notably a credit bureau integration that cut compliance costs by over 50% and boosted acceptance rates from 50% to 98%. Skilled in Scrum and Agile, she drives measurable process improvements (backlog reduction, story-point planning) and routinely translates stakeholder needs into clear technical specs. Polina blends strategic thinking with data-driven decision making, having applied R and SQL for data quality analysis early in her career. Based in St. Petersburg, she favors collaborative team dynamics (and contact sports) while retaining the ability to make independent, risk-aware choices. Her background in sociology and social informatics gives her a rare mix of user-centered insight and technical rigor.
