Dec 2020 - Apr 2023 • 2 yrs 4 mos

I am a skilled Unreal Engine 5 developer with experience in Blueprint debugging, gameplay systems development, multiplayer replication, and performance optimization for UE5 projects. I have worked on fixing complex Blueprint bugs, character movement systems, AI behavior trees, inventory systems, save/load systems, widgets/UI, animation Blueprints, interaction systems, and shooting mechanics. My expertise includes troubleshooting packaging failed errors, fatal errors, startup crashes, plugin conflicts, memory access violations, shipping build issues, and multiplayer networking problems such as RPC issues, server/client desync, inventory sync, and animations not replicating. I help indie developers and game studios improve gameplay stability, optimize FPS performance, debug Blueprint systems, and repair broken UE5 projects quickly and professionally. I focus on delivering reliable solutions, clean debugging, optimized gameplay logic, and fast communication to ensure projects run smoothly across single-player and multiplayer environments. I also provide support for Blueprint optimization, lag reduction, replication fixes, AI system debugging, and gameplay improvements for Unreal Engine projects across different genres including FPS, multiplayer, survival, and simulation games.
