About Estelle

With a dual background in graphic design and senior front-end development (including 3 years at Voodoo), I position myself at the intersection of product and technology to bring fluid and performant interfaces to life.

What I bring to you concretely:
  • Design Systems:Design, development, and organization of your component libraries (React.js / Vue.js) to ensure product consistency and scalability.
  • UI/UX Integration:Faithful translation of your Figma mockups into clean, optimized, and maintainable code, with strict adherence to ergonomics, typography, and animations.
  • Product/Tech Link:Close collaboration with your designers from the conception phase to anticipate technical constraints and streamline the development process.

I am available to support you in the development of your interfaces and the structuring of your components.

Estelle is an excellent team member: proactive, efficient, motivated, rigorous, and unafraid of challenges or refactoring tasks. She also brings a lot of good humor to the work environment and knows how to diplomatically question things that could be improved. Her mastery of React and design makes her a rare and relevant profile for effective communication with product or UX. I highly recommend her and hope we can work together again!
