Andrey Svalov

I’m a data analyst focused on turning messy data into decisions leaders can act on. I build executive-ready analytics with SQL and BI tools, and I’m hands-on about writing real queries and models against real engines.

At Gazprombank, I developed and delivered executive dashboards in Power BI and Yandex DataLens for PPP project metrics, employee timesheets, and resource utilization. I led an end-to-end ML-driven implementation—defining requirements, running data collection and validation for training, benchmarking with A/B tests, and proposing system enhancements—resulting in 50% improvement in data processing quality and a 20% increase in model accuracy.

I also find inefficiencies and translate business needs into technical solutions, including BI, RPA, and system integrations. From large-scale PPP datasets, I uncover insights and trends, and I automate analytical reports to support business and operational teams while strengthening data quality and KPI frameworks.

Earlier, as an AI Trainer at Yandex (contract), I contributed analytical work and creative problem solving. I’m currently building an open, hands-on platform to learn data skills—focused on writing SQL and Python and learning through instant feedback—so I can keep shipping practical, measurable analytics.
