During October 2025, Muhiddin Dalycity developed core backend features for the 250908-NET/Daunting-Devitos repository, focusing on a scalable multiplayer Blackjack game. He implemented a user management system using GUID-based IDs to enhance data integrity and distributed compatibility, refactoring the repository and standardizing identification across the codebase. Leveraging C#, ASP.NET Core, and Entity Framework Core, he built a room-based game engine supporting full game lifecycles and integrated a DeckApiService for card management. Comprehensive REST API endpoints and robust unit tests using xUnit and Moq ensured reliable room management and gameplay, resulting in maintainable, test-driven code with strong multiplayer support.
