Senior Unity game developer: I build high-performance Unity multiplayer games for Android, iOS, PC, and WebGL using Photon, Firebase, AWS, and PlayFab. Specialized in multiplayer systems, gameplay programming, optimization, matchmaking, and live game features. Need a Unity developer who can take your game from concept to a stable, store-ready release without the rebuilds and bug-fires that come from rushed architecture? I'm a Senior Unity Game Developer with 10+ years of experience, including time at Mega Cat Studios (USA), building 2D and 3D games, mobile apps, multiplayer systems, and AR/VR experiences that hold up in production, not just in a demo. 🔹Core Development Services: Unity 2D/3D Game Development : full game builds from prototype to release, clean C# architecture, scalable systems Mobile Game Development (Android & iOS) : store-ready builds, deployment, Google Play & App Store compliance Multiplayer Game Development : real-time multiplayer using Photon (Fusion/PUN), Mirror, and Unity Netcode; matchmaking, lobbies, PvP and co-op systems, latency-aware sync AR/VR/XR Development : AR Foundation, Vuforia, ARKit, ARCore; immersive apps, training simulations, GPS-precision AR tools WebGL Game Development : browser-based builds with no native app overhead, optimized for web performance Game Optimization & Bug Fixing : FPS profiling, memory management, load-time reduction, refactoring unstable code for production release Game Consultation & Design Documents : technical feasibility reviews, architecture planning, GDD creation for studios and startups Monetization & Live Ops : in-app purchases, ads integration, PlayFab and Firebase backend setup, analytics and player retention systems 🔹 Proof it works, not just a claim: Multiplayer that holds up under real players : Built MetaTope, a real-time multiplayer mobile game using Photon, handling matchmaking and latency-aware sync for concurrent players across regions. AR that works on real devices, not just the demo : Developed Wonder AR (AR Foundation + Vuforia) and a GPS-precision AR geo-location tool, balancing immersion against device fragmentation and real-world GPS drift. Certified, not just experienced : Unity Certified Professional (Programmer) and Unity Certified Associate (Game Development), backing 9+ shipped portfolio projects spanning FPS shooters, physics-based games, and simulation titles. Tech stack: Unity 3D, C#, Photon Fusion/PUN, Mirror, Unity Netcode, AR Foundation, Vuforia, Firebase, PlayFab, WebGL, RESTful APIs. How I work: clear scope and realistic timelines agreed before I write a line of code, regular progress updates instead of radio silence, and production-quality architecture built to be extended later not thrown away after launch. Whether you need a hyper-casual mobile game built fast, a multiplayer system that actually stays in sync, an AR/VR prototype to pitch to investors, or an existing Unity project debugged and optimized for release, send me a short brief. I'll tell you honestly whether it's a fit and how I'd approach it, before you spend a Connect on a proposal. 📩 𝐋𝐞𝐭’𝐬 𝐓𝐚𝐥𝐤 If you’re looking for a senior Unity developer who can think, build, optimize, and deliver, I’d be happy to review your project.
