Unreal Engine Multiplayer & Gameplay Systems Developer I specialize in building scalable multiplayer systems in Unreal Engine 5 using C++ and Blueprints. My work focuses on server-authoritative architecture, replication stability, and production-ready gameplay systems. If your Unreal project has unstable multiplayer, messy replication, or hard-to-maintain gameplay code — I restructure it properly. 🔥 Unreal Engine • Multiplayer architecture (Listen / Dedicated / EOS / Steam) • Replication debugging & optimization • Shooter systems (weapons, ammo, recoil, inventory) • Advanced animation systems (Motion Matching, traversal, combat logic) • AI systems (Behavior Trees, EQS, boss logic) • Performance optimization (Nanite, LODs, scalability, memory profiling) I design systems for scalability and long-term maintainability — not quick fixes. 📱 Unity (Mobile & Cross-Platform) In addition to Unreal, I develop structured Unity projects, mainly for mobile and casual games: • Clean C# architecture (SOLID principles) • Modular gameplay systems • IAP integration (Google Play / App Store) • Ads integration (Unity Ads / AdMob) • Reward systems & progression logic • Store-ready build preparation 🧠 Technical Core C++ (Unreal Engine systems) C# (Unity architecture) Multiplayer networking Gameplay system design Codebase refactoring & stabilization Performance profiling Git workflow 🎯 How I Work I don’t just complete isolated tasks. I evaluate project architecture and improve stability, structure, and scalability. Clear communication. Clean code. Long-term thinking.
