Freelance React Frontend Developer in Madagascar

What I build with React

  • ✓React modules within an existing SaaS platform
  • ✓Interactive data visualization (a family tree with a custom layout algorithm and SVG links)
  • ✓Next.js applications with server rendering (this portfolio)
  • ✓Data fetching and state with TanStack Query, Zustand and Zod
  • ✓A recent personal project: a Trello-like app with a React frontend and a Symfony API

Frequently asked questions

React or Next.js for my project?
React alone for an interface inside an existing application, Next.js when you need server rendering, routing and SEO out of the box.
Can you migrate an app to React 19?
Yes. The upgrade from React 18 is mostly incremental: we update the dependencies, fix the deprecations, then adopt the new features where they bring value.
Do you work remotely from Madagascar?
Yes. Based in Antananarivo, I work remotely with teams in France and across Europe, with 1 to 2 hours of time difference with Paris.
