While Witco was updating its product identity and shifting to React, they wanted to use this change as an opportunity to tackle their design system project. It was perfect timing, but they were unsure how to get started.

Overview
I joined Witco during an 8-month ride to build Play, the design system. I led the project from discovery to execution in 3 main phases:
- Discovery and research
- Execution of a quick Proof-of-Concept to learn together, from conceptualizing to shipping a component.
- Iterative delivery
My responsibilities were threefold:
- Steering the project with the guidance of Galaxy (VP of Product) and the support from the Product Owners and Tech Leads.
- Designing the assets in Figma, enriched by feedback and challenges from Jérôme and Cédric, our Senior Product Designers, who rigorously tested the design system in features they were designing.
- Engineering, which ranged from architecting the mono-repository and packages to front-of-the-front-end development, particularly the styling of React components and design tokens. Here, I worked closely with Lilly, who handled logic implementation and ensured code quality, and Franco, who tested the components within the features in development.
