Developed a fully replicated, optimized multiplayer weapon customization system in Unreal Engine 5 using C++ featuring modular attachments, weapon specific and platform exclusive compatibility, real time stat updates, dynamic mesh swapping, material customization, Aim Down Sights configuration, and persistent loadout saving/loading.

Implemented asynchronous asset loading for efficient memory usage and seamless runtime customization while minimizing load times and supporting scalable expansion of weapons and attachments.
