Senior Unreal Engine Developer | C++ Gameplay, GAS, UI, Multiplayer

I help build production-ready Unreal Engine gameplay systems, multiplayer features, UI, dedicated servers, and polished in-engine experiences. With 8+ years of Unreal Engine experience, I focus on strong technical execution, clean gameplay architecture, and reliable systems that can scale from prototype to production. What I can help with: - Unreal Engine 4/5 gameplay programming - Gameplay Ability System implementation - C++ gameplay systems and Blueprint integration - Gameplay Framework architecture - Multiplayer replication and server-authoritative gameplay - Dedicated server setup and online multiplayer features - Player abilities, combat systems, weapons, progression, and interaction systems - State Tree, AI behavior, NPC logic, and gameplay decision systems - Common UI, UMG, HUDs, menus, and UMG ViewModel/MVVM workflows - Animation integration, input systems, and responsive character mechanics - Performance optimization, debugging, profiling, and gameplay polish - Turning game ideas into playable, testable, production-ready systems - Publish games on Steam via Steamworks My Approach: Understand the gameplay vision → define core mechanics → plan the gameplay architecture → build clean C++ systems → expose designer-friendly Blueprint workflows → implement multiplayer/replication → integrate UI and animation → test → optimize → polish.
