Attila K.

I build gameplay systems, multiplayer features, and UI in Unreal Engine using C++ and Blueprints. I can help develop a new feature, troubleshoot an existing project, or build the foundations for a playable prototype. I have around five years of hands-on Unreal development experience. On a multiplayer FPS project, I owned core gameplay, networking, and UI—from server-side rewind for lag compensation to an extensible weapon system, Gameplay Ability System integration, replicated scoreboards, and Redpoint EOS online services. Through my company, Green Bear Software, I’m also developing Evolution: The Chronicles of Fire, a top-down survival action RPG. My work includes GAS-based combat and attributes, StateTree enemy AI, procedural dungeons, building systems, and gameplay UI. My main areas of work include: • Gameplay programming with C++ and Blueprints • Multiplayer replication and lag compensation • Gameplay Ability System for players and AI • CommonUI/UMG and gameplay-driven interfaces • Behavior Trees, State Trees, and character animation integration • Unreal plugins and backend/game-service integrations I enjoy taking ownership of a feature, understanding how it fits the existing project, and making it straightforward for other developers and designers to extend. Before game development, I spent five years as a Customer Quality Engineer at Bosch. That experience shaped my approach to debugging, clear communication, and systematic problem-solving. Tell me about your project, its Unreal version, and the feature or issue you need help with. We can define a focused first milestone and clear completion criteria.
