# Antoine Deshoux — Product Designer, Design System Expert & Design Engineer

> Paris-based freelance designer who works at the intersection of Product Design, Design Systems, design engineering and AI design ops. 8+ years shipping consistent, high-performing user experiences for startups and enterprises including Carrefour and Malt.

## About

Antoine Deshoux is a freelance designer operating across four connected pillars:

1. **Product Designer** — end-to-end product design: user research, information architecture, interaction design, UI, prototyping, and shipping polished interfaces with engineering.
2. **Design System Expert** — architecting, auditing, migrating and scaling design systems (design tokens, component libraries, governance, documentation) for teams ranging from startups to enterprise organizations.
3. **Design Engineer** — works in code as well as in Figma: React and TypeScript component libraries, design tokens pipelines, and design-to-code workflows that keep the Figma library and the shipped UI in sync.
4. **AI Design Ops** — designing AI-native products and AI-assisted design workflows: prompt architecture, model-aware UX, evaluation loops, interfaces for LLM and generative tools, and helping design teams integrate AI into their daily practice.

Based in Paris, France. Works remotely across Europe and internationally. Bilingual (French native, English fluent).
