Developed foundational backend and frontend features for the MalosAlex/UBB-SE-2025-924-2 and HorvatAris/UBB-SE-2025-Steam repositories, focusing on scalable API scaffolding, user profile management, and forum infrastructure. Leveraged ASP.NET Core MVC and C# to implement secure user account flows, settings management, and RESTful services, while introducing interfaces and service proxies for forum post and comment operations. Addressed a forum scoring bug to ensure accurate post rankings and stabilized build processes through codebase cleanup and dependency fixes. The work emphasized maintainable architecture, robust API design, and seamless user experience, supporting both Steam Web API consumers and community forum users.
