# Marsel Bait

> Product and brand designer based in Tokyo. Four years as a product designer at Enjin, leading the 2023 redesign of a bilingual recruitment platform across three product verticals (research, information architecture, design system, brand), then design-led work at Miraidukuri. I also build AI-native tools: published MCP servers on npm that AI agents call directly, so I am not only a designer who uses AI, I build the tools the AI itself uses.
