Description

Freelance React / Next.js Developer – Performant and maintainable web interfaces with Typescript

Need a robust front-end to accelerate your web product? I step in as a freelance React / Next.js developer, with an approach focused on performance, code readability, and user experience. My goal: deliver a reliable, scalable interface ready for production.

I specialize in React.js, Next.js, and Typescript, with over 13 years of experience on various projects: SaaS, B2B platforms, marketplaces, and back-offices. I work on greenfield development as well as taking over existing projects or improving codebase quality. I integrate easily into your product or tech teams, with autonomy and methodology.

Throughout my assignments, I have supported startups, SMEs, and large corporations on complex front-end projects: migration to Next.js, implementation of design systems, pixel-perfect integration from Figma, front-end architecture redesign, and optimization of REST API calls. Each intervention is designed to lay a healthy and sustainable foundation.

I deliver a turnkey front-end, built to last: responsive, typed with Typescript, structured into reusable components, with clear separation between UI, business logic, and effect management. Particular attention is paid to code readability, interaction fluidity, and good performance practices.

My preferred stack: React, Next.js, Typescript, Tailwind, Zustand, React Query, REST API, Jest, Playwright, CI/CD, GitHub Actions, code splitting, lazy loading, Lighthouse. I systematically apply logic of testing, automation, and web performance to guarantee you a stable and maintainable product.

Looking for a React / Next.js developer capable of quickly delivering a reliable and scalable front-end? Let's chat via video call to define your needs. I usually respond within 24 hours.
