Summary
🤩
Rockstar🎓
Top SchoolFatih Mar is a Principal Software Engineer based in London with a decade of experience building multiplayer networking and cloud-backed online services for AAA games and tools. He has driven core networking systems at studios and platforms including Unity, Rocksteady, and Splash Damage, and currently leads technical architecture and multiplayer mechanics in Unreal Engine 5 at Lighthouse Games while directing engineering at Network Assembly. Fatih’s contributions to prominent open-source Unity projects—such as implementing and refactoring RPC systems and improving Netcode docs for Unity’s multiplayer stack—showcase a rare blend of low-level protocol work, engine integration, and clear technical writing. He’s equally comfortable optimizing server performance as he is shaping SDK design, and often surfaces non-obvious reliability and serialization improvements that prevent costly runtime issues. Known for translating complex distributed-system constraints into pragmatic engine-level solutions, he pairs hands-on implementation with technical leadership across teams.
