Owned the full lifecycle of Deus CLI, from initial concept and architecture to development and launch, grounded in Unix Philosophy. Defined a clear distinction between human-centric and agent-centric CLI design, shaping the product's direction from day one.

Successfully shipped Deus CLI in just four weeks, enabling designers and diverse makers to leverage AI-powered workflows through Deus as a design tool — unlocking a new class of creative automation that was previously inaccessible from the terminal.

Ported Deus's WebSocket-based patch logic to the CLI, enabling full read and write access to canvas design assets. This brought the same real-time collaborative editing model from the web client into the terminal, dramatically improving the internal developer experience.

Highlights

  • End-to-end ownership: concept, architecture, development, and launch in 4 weeks
  • Design philosophy rooted in Unix principles, separating human-centric and agent-centric interaction models
  • Empowered designers and makers to integrate AI into their workflows via Deus as a design tool
