I’m Lorenzo Grasso, a game programmer focused on building gameplay systems, AI, and solid multiplayer infrastructure—especially with Unreal Engine (C++) and Unity (C#). I enjoy turning game design ideas into reliable, scalable code, whether that’s server-authoritative combat, wave-based enemy encounters, or modular frameworks that make development faster. I’ve worked across the full gameplay loop: from matchmaking, persistence, and cloud saves to designing reusable ability systems, movement/aiming/shooting mechanics, and data-driven boss or enemy behaviors. I’m proactive and collaborative, and I like communicating clearly with teams while solving problems quickly—so projects can move from prototype to a polished, testable experience.…I’m Lorenzo Grasso, a game programmer focused on building gameplay systems, AI, and solid multiplayer infrastructure—especially with Unreal Engine (C++) and Unity (C#).
