Need a senior Unity game developer to build, stabilize, or optimize a mobile game? I bring 10+ years of Unity and C# experience, including more than 5,400 verified Upwork hours. I work across the full production cycle—from prototypes and gameplay systems to performance optimization, backend integration, Android/iOS builds, and release preparation. I can help you with: • 2D and 3D mobile game development in Unity • Gameplay systems, UI, progression, animation, and scalable architecture • Debugging, refactoring, and rescuing existing Unity projects • Profiling and performance optimization for mobile devices • Multiplayer and backend integration using Photon, Firebase, and PlayFab • Android and iOS builds, third-party SDKs, and deployment issues My experience includes leading a development team on a multi-year project, building gamified mobile applications, extending existing games, implementing multiplayer and localization, and solving complex Unity, Android, and iOS problems. My approach is practical: understand the existing project, identify the highest-risk technical problems, communicate clearly, and deliver maintainable C# code without unnecessary rewrites. Core stack: Unity, C#, Android, iOS, Addressables, Firebase, PlayFab, Photon, Git, and CI/CD. Send me your project brief, current build, or bug list. I’ll help you identify the safest and fastest path to a stable, production-ready release.
