At Т-Банк’s Personal Finance team, I ran A/B tests from design through analysis. One test of a button linking to spending categories on payment success screens significantly increased the target metric and active users; the feature was rolled out to the full audience.
I analyzed user journeys and CES/CSAT survey responses to help product managers prioritize improvements. I also contributed data integration and user classification criteria to the “traffic light” metric for prioritizing user problems.
I supported two key product dashboards and participated in their migration from PostgreSQL to Trino, reducing average data processing time by about 70%. My work draws on statistics and econometrics, which I studied at НИУ ВШЭ and applied in my thesis on imputing non-random missing survey data.
