Lev Perschin developed foundational domain modeling and billing enhancements for the Hochfrequenz/BO4E-dotnet repository over a two-month period. He introduced two new business objects, Leistungskurvendefinition and Schaltzeitdefinition, integrating them into the core BusinessObject framework using C# and object-oriented programming principles. His work included refining data handling and list management, as well as extending Rechnungsposition to support detailed surcharge and discount calculations. By refactoring surcharge and discount logic to type-safe enums, Lev improved code quality and data integrity. These changes established a scalable base for future business rule enforcement, analytics, and more accurate reporting within the backend system.

October 2024 delivered foundational domain modeling enhancements for Hochfrequenz/BO4E-dotnet, focusing on performance-related business objects and improved data handling. The work establishes a scalable base for future rules, reporting, and configuration of performance definitions with minimal surface area changes to existing code. Key outcomes include integration of new performance-related BOs into the core BusinessObject framework, and minor refinements to related definitions to ensure consistency and list handling. These changes reduce future integration effort and unlock more accurate configuration and reporting for business users.
