Dzmitry Baranau

I've built end-to-end analytics infrastructure for subscription products at Ruby Labs, GetQR, and Hint App, turning multi-source data into reliable reporting for product, marketing, billing, and growth decisions. I designed data warehouse architecture from raw data through staging and marts, automated ETL/ELT pipelines, and implemented unified tracking across web and app products. My work reduced ad-hoc time-to-insight from days to hours and supported double-digit improvements in core product KPIs through experimentation and near-real-time reporting. At Tango Me, I drove hypothesis-led analysis across engagement and virtual-currency monetization funnels, running full-cycle A/B tests and delivering feature-impact recommendations on retention, engagement, and monetization. Earlier at EPAM Systems, I led reporting and analytics work for global delivery teams, mentored three analysts, and automated SAP Concur workflows in partnership with Finance, HR, and Procurement.
