Description

Your React/Next.js app is slowing down, your MVP needs to launch fast, or a legacy front-end is holding your team back? That's what I've been solving for 9 years.

Lead front-end developer, I design and evolve high-performance web applications for startups and large companies (France, USA, UK).

What I do best:

- Front-end migration and refactoring: Next.js (App Router), React, TypeScript

- Monorepo architecture (Turborepo), design system

- Web performance: audit, Core Web Vitals, SSR

- API and data: GraphQL, Apollo Server, Node.js / NestJS

- AI integration (OpenAI, Claude, Vercel AI SDK)

- Quality: tests (Jest, TDD), accessibility

References:

- Mini Studio (New York) — 1st front-end dev for an AI SaaS: MVP in production in 14 days, architecture, Turborepo monorepo

- Football Index (London, fintech) — real-time trading platform refactoring, led front-end team from 0 to 10

- Storengy / ENGIE — front-end in a large enterprise environment (energy sector)

Clear communication with product teams and non-technical profiles, total autonomy in remote. Fluent English (9 years with US/UK teams).

Based in France, 100% remote, occasional travel possible (Paris or elsewhere). Short or long missions, full-time or part-time, fast start.

Tell me about your project: I usually respond within an hour.
