About J World

My role at J World

As the creative designer at J World, I led end-to-end product design for the 2025 S/S collection, launched 7 new backpacks, bags, and accessories from concept to market and designed 30+ bag printing patterns, with 11 new patterns successfully launched for the 2025 S/S season. Also, J World attended 2025 NY Toy Fair with new products that I designed.

For the production, I produced 20+ detailed tech packs and coordinated directly with manufacturers in China to ensure on-time delivery, quality control, and production.


In terms of marketing, I directed model photoshoots in collaboration with professional photographers and models to create high-quality marketing assets.

Currently, I'm working on the 2026 S/S season, so stay tuned!
