About me
Hi! I'm Kai Xian Lan Ji, a Gameplay & Systems Designer based in Spain, with hands-on experience developing projects of different scopes using Unreal Engine 5 and Unity.
I specialize in gameplay systems, combat feel, progression, and player experience design, with a strong focus on translating design ideas into playable and iteratable experiences. My background in implementation and prototyping allows me to collaborate closely with multidisciplinary teams and rapidly test gameplay concepts in-engine.
I enjoy analyzing how mechanics, systems, and player behavior interact to create meaningful gameplay experiences, and I'm particularly interested in action, competitive, and systems-driven games.
