I’m Paya Do, a Principal Product Designer & design leader based in Stockholm. Previously I lived in Tokyo, San Francisco, Saigon, Singapore and New York. I left my political science career to become a designer and I haven’t looked back. I still love sciences, function with both the left and right hemisphere of the brain.

I work mainly on Figma, and am still pushing idea on a canvas.
Over the past year I've welcomed the practice of bringing AI into design operation in concrete ways: authoring agent skills (SKILL.md) for production design workflows, building custom Notion AI agents for user research synthesis, integrating MCP servers into design system tooling, and developing multi-skill architectures that generate structured deliverables from design system inputs.

I also produce music and make audio effect plugins when I am free.
