Russian FederationWhat I'm looking for
At Sber CIB, I lead an eight-person analytics team and grew BI product DAU 2×+ while maintaining a 4.9/5 CSI. I've shipped 36 dashboards, led a Qlik Sense-to-Navigator BI migration with zero downtime, and launched an LLM reporting pilot that delivers metrics directly in chat.
Across Sber, Novartis, and financial reporting projects, I've built ETL pipelines, data models, automation, and decision-ready reporting. I also founded HireHero, an IT career platform, and enjoy turning complex data workflows into products people actually use.
