Hello, I'm Seo!
I'm a Senior Game Designer with 8+ years of experience shipping globally launched titles across PC and Mobile.
I’ve had the chance to work across both beloved IPs like Marvel and Mabinogi, and original titles like Warhaven — diving deep into level, systems, and encounter design (the whole toolkit!).
With a background in Computer Science and Media Arts,
I love solving tricky problems and thinking through design with both creativity and logic.
