In November 2025, G. Bondarenko developed the foundational scaffolding for a Financial Simulation Program in the soomrack/MR2025 repository, focusing on modeling financial scenarios for decision support. Using C++ and applying skills in financial modeling and simulation development, he implemented an initial simulator featuring two personas, Ivan and Petya, to represent salary, expense, and apartment-purchase decisions. This groundwork established a reusable architecture for rapid prototyping of financial outcomes, supporting future enhancements such as additional personas and complex rules. The work demonstrated depth in system design, enabling product and finance teams to forecast and analyze diverse financial decision-making scenarios efficiently.
