About Marine

Front-End Developer with **5 years of experience**, I design high-performance, accessible, and pixel-perfect interfaces.

My expertise revolves around **React.js, Next.js, and TypeScript**. Throughout my missions, I've had the opportunity to build reusable components, design systems documented in Storybook, and integrate headless CMS like Strapi to empower business teams.

Sensitive to animations and micro-interactions, I use advanced CSS and Motion (Framer Motion) to create **engaging interfaces that enhance user experience**.

During my last mission at Beta.gouv / ADEME (2 years, full remote), I contributed to the development of the Next.js public site for theTerritoires en Transitionsplatform, a tool for managing ecological transition for local authorities. I co-built a design system of 30+ components documented in Storybook, integrated the Strapi headless CMS for the communication team's autonomy, and implemented PDF export on dynamic data (react-pdf).

Before that, I worked for a year atAirbus Commercial(via Capgemini) on an application for tracking aircraft tests, related to pre-delivery traceability requirements, involving offline mode (IndexedDB), UX/UI redesign, and Redux Toolkit migration.

My Approach:pixel-perfect rigor, clean and documented code, close collaboration with POs and designers. I have always worked hand-in-hand with teams to align business vision with technical possibilities, keeping user experience at the heart of my work.

Available immediately - remote or flex-remote (South-West France).
