Mikhail Arzumanov

Built a UE5 World Partition chunk streaming system for dense open-world areas using manager/coordinator architecture, task queues, and HISM/foliage caching, reducing freezes and smoothing chunk activation where FPS previously dropped by up to 70%. Developed editor and debugging tools for centralized async streaming coordination across the world, improving control over loading workflows during development. Designed and implemented reusable warehouse and shop UI architecture with sorting, pagination, cached item data, and Design Data Asset-based visual configuration. Extended the warehouse UI into weapon and logistics shop flows, saving more than 1.5 months of development time through feature reuse. Implemented NPC loot inventory replacement logic with level-based generation or manually assigned loot while preserving the character's visual appearance.
