“Unreal Engine (UE5) gameplay engineer who built large-scale open-world RPG systems end-to-end, including world streaming, AI ecosystems, and networked combat. Strong multiplayer focus: used Unreal Insights/custom profilers to identify replication/physics bottlenecks and delivered >40% frame stability improvement via relevancy checks and proxy-physics strategies, plus deterministic fixed-step simulation with rollback/state correction.”

“Unreal Engine gameplay/systems developer who owned core systems like NPC AI (AI Controller/Behavior Trees) and loot/itemization/economy, plus progression/difficulty frameworks for a shipped title. Notably drove mobile performance/packaging work, citing a ~75% reduction in AAA Android export size to get a high-end console-quality build under 500MB, including a custom Photoshop macro pipeline to process a massive texture library. Also prototyped advanced MetaHuman features (secure WebSocket, speech/visemes, expressions) using Blueprints and Unreal Editor Python utilities.”
