Ilijas S.

I am a Lead Unreal Engine 5 Systems Engineer specializing in complex architecture, server-authoritative multiplayer logic, and performance optimization. I single-handedly architected, packaged, and shipped a commercial multiplayer survival title to a global storefront. My core technical expertise includes: • Engineering server-authoritative network replication and RPCs for stable, synchronized environments. • Implementing and tuning native UE5 physics, handling dynamic mass, buoyancy, and projectile collisions. • Deep-dive profiling and debugging to untangle broken logic and optimize performance. Whether you are building a data-heavy industrial simulation, or you need a senior-level architect to debug a mid-development project, I deliver clean and stable executables.
