I build high-performance SAP BI and planning solutions for enterprise-scale data.
BelarusWhat I'm looking for
I've delivered SAP BI and planning solutions for Fortune 500 companies including Bayer, Adidas, Priceline, and Coca-Cola HBC, completing more than 10 projects used by 7,000+ people.
At iTechArt Group, I designed row-level security based on time-dependent organizational structures, projects, and customers, reducing legacy-system manual changes. I also built a BW/4HANA self-service flat-file upload tool with master-data checks, error logs, and data-quality controls.
At EPAM Systems, I led 18 BW developers, replicated and post-processed around 50 SAP Datasphere assets totaling 2 TB from S/4HANA into Google BigQuery, and improved 40 reports running on 30 billion rows by 32%. I also reduced Tableau dashboard performance from 105 seconds to 10 seconds for complex HANA-based reporting.
Since 2008, I've combined SAP BI development with business analysis, stakeholder communication, SQL training, and technical talks. I work across SAP BW, BW/4HANA, HANA, Datasphere, SAC, Tableau, Power BI, and modern development tools including Git, Python, Node.js, and React.
