Backend Engineer · Game systems programming in UE5 C++
I build backends that survive scale, and personal projects that explore game systems programming.
Production work is in NestJS / TypeScript with PostgreSQL, Redis, Docker, and AWS — applying Clean Architecture and Domain-Driven Design to write code that survives team turnover.
Personal focus is Unreal Engine 5 C++ multiplayer replication, Gameplay Ability System, and editor tooling with Slate.

};→ Lunaris — mission orchestration platform. DAG-based loop prevention (DFS tricolor + explicit stack), event-driven pipelines, SHA-256 versioning, full Docker deployment.
→ lunaris-app-plugin — UE5 editor plugin consuming the Lunaris API.
