Senior🎓
Top SchoolJohn Mcelmurray is a Principal-level gameplay programmer and technical artist with 13 years of experience building online multiplayer experiences in Unreal and Unity, now focused on R&D gameplay engineering at Riot Games. He led core "3Cs" systems, animation pipelines, and a cross-platform input and UI framework for a shipped co-op title based on The Dragon Prince, enabling hundreds of abilities and nearly 100 characters from a single shared architecture. Comfortable in both C++ and C#, he has hands-on experience customizing networked movement, prediction/rollback with Unreal's Gameplay Ability System, and profiling for performance, bandwidth, and memory. Earlier work at Microsoft produced a Unity-based visual effects and rewindable timeline prototype that shipped into consumer products, showing his ability to take prototypes to market. His GitHub contributions include practical gameplay prototypes such as a third-person camera and character controller, reflecting a taste for polishing player-facing systems and asset integration. A 4.0 CS graduate from Virginia Tech, he pairs deep technical craft with a strong eye for art-driven game feel.
