About Cécilia

👋 Passionate about programming, I have been working as a full-stack developer since 2021.
Also trained in interface design, I have a solid graphic culture.

Expertise in the media industry.
Interested in current affairs, I work for several media outlets (Les Jours, Mediapart) and have a very good understanding of the specific challenges of this field. Curious and committed, I also have several experiences in the associative (Horizon, Lieux Communs) or cultural (Le Signe - national center for graphic design, Agence Nabokov) sectors. Involved in the  Gyn&co collective, which fights against gynecological and obstetric violence, I am also sensitive to health and access to care issues.

Expertise in Typescript and JS/TS frameworks.
Throughout my various experiences, I have worked on different ecosystems, technologies, and frameworks. Although I have had the opportunity to work on PHP/Symfony and API Platform, my expertise and preference lie in using Typescript and various TS/JS frameworks such as Next.js, React, NestJS, and Node.js. I am familiar with Docker and Git, REST API development, and the use of React Admin and Tiptap libraries.

Skills for every stage of design.
From my previous experiences as a graphic designer, I can participate in the various stages of design. Familiar with product culture, I offer to:
​✺ Write specifications
​✺ Create mockups and develop your application
​✺ Maintain and improve an existing product
​✺ Temporarily strengthen your team
