Iulia Szarics developed and enhanced backend features for the vodaioan03/UBB-SE-2025-927-1 repository, focusing on robust exercise modeling and roadmap-centric section management. She applied C# and ASP.NET Core to refactor namespaces, introduce enums, and implement validation logic, improving data integrity and API consistency. Her work included designing RESTful APIs with standardized routing, integrating dependency injection for modularity, and migrating tests to MSTest for reliability. By addressing error handling and refining endpoint conventions, Iulia increased maintainability and reduced onboarding friction. Her contributions demonstrated depth in API design, backend development, and service-oriented architecture, resulting in a more reliable, testable codebase.
