I've built Java/AnyLogic digital twins at NFP Financial Solutions for dry port, mining, central bank, and Magnit warehouse operations, modeling logistics flows, fleet capacity, and interactive client-facing visualizations.

Previously, I designed and deployed Spring Boot applications at LiveInvestingGroup and ITMO University, covering database architecture, REST APIs, role-based access, parsers, and Docker deployments. My seven years in banking help me translate ambiguous business requirements into practical software and communicate directly with clients and stakeholders.
