About Yoann

Need to launch an MVP or strengthen your team on a modern stack? After several years in business, I am going freelance with a clear objective: to deliver robust, clear, and ready-to-ship code

What I bring to your project:

Web & Performance: Development with React and Next.js (App Router). I design fluid interfaces, optimized for SEO and accessibility, with an architecture designed to last.

Mobile & Deployment: Via React Native and Expo, I develop your mobile app for both Android and iOS. I handle the entire build and deployment chain via EAS: managing certificates and submitting to the stores to avoid any technical blockers.

Infrastructure & Quality: I systematically integrate TypeScript and Tailwind CSS. To secure your updates, I configure your continuous deployment pipelines (GitHub Actions, Vercel) so that they are automatic and tested.

My mastery of Node.js (NestJS, Prisma) allows me to ensure smooth integration with your backend and PostgreSQL databases.

Why collaborate with me?

Newly freelance, I offer a tailored rate to build my first references on Malt, with the rigor acquired on large-scale projects. I prioritize transparency: daily communication, documented code, and technical honesty to define the best strategy together.

I help scale-ups deliver 2x faster without increasing the tech team

Technical Stack:

Front-end: React, Next.js, Tailwind CSS, TanStack Query.

Mobile: React Native, Expo, EAS (Build & Submit).

Back-end: Node.js, NestJS, Prisma, PostgreSQL.

Tools & Ops: Git, Docker, CI/CD (GitHub Actions, Vercel).
