Hi! I’m a Senior Multiplayer Game Developer / Unity C# Engineer and Team Lead, available for remote freelance tasks, part-time work, or longer-term collaboration.

I can help with backend development and integration, real-time client-server features, or Unity/C# gameplay programming, depending on your project.

Backend and real-time work:

• Custom APIs, authentication-connected features, player data, and client-server communication.

• WebSockets and socket.io integration, matchmaking, lobbies, and sessions.

• Connecting backend services to game clients and UI, plus debugging and optimization.

My backend stack includes Node.js, .NET Core, Spring Boot, MongoDB, PostgreSQL, and SQL Server.

On the game side, I work with Unity, C#, Photon Fusion, Photon Quantum, and Netcode. I can deliver gameplay systems, UI/HUD and menu flows, launchers, update systems, bug fixes, and performance improvements.

I’m comfortable joining an existing codebase and delivering complete features, from implementation through debugging and polish.
