Deus

A design editor built on web canvas with real web components — bridging design and development by eliminating handoff, born from how the Toss team works.

Design Tool

Deus is not just a design editor — it's a product that embodies how the Toss team works. Unlike Figma, Deus places real web components directly on a web canvas, fundamentally reducing the handoff between design and development.

I led engineering on core feature development including in-app prototyping and image export, while also driving the AI transition strategy through initiatives like Machina (a built-in AI agent) and CLI tooling.

Highlights

  • Web canvas editor with real web components — no design-to-dev handoff
  • Feature development: in-app prototyping, image export, and more
  • Machina: built-in AI agent for design assistance
  • Led engineering while proposing AI transition strategies (Machina, CLI)
