J’aide les entreprises à transformer leurs enjeux business en solutions techniques efficaces, que ce soit pour développer un MVP, renforcer une équipe lors d’un pic d’activité, ou stabiliser / refactoriser une application existante.

Mes domaines d’intervention :

- Renfort d’équipes en période de forte charge ou sur des projets critiques
- Refactorisation, debugging et amélioration de codebases existantes
- Conception d’architectures scalables et orientées produit

Je mets un point d’honneur à écrire du code propre, performant et durable, toujours aligné avec les objectifs business.

Full Stack Developer – React | Node.js | NestJS | Prisma | MongoDB

I help companies turn business challenges into efficient technical solutions, whether it’s building an MVP, reinforcing a team during activity peaks, or stabilizing and refactoring existing applications.

I’m used to real-world constraints: deadlines, business priorities, technical debt, and long-term quality. My role is to make the right technical decisions to deliver fast while keeping systems maintainable.

What I do:
- Build MVPs and full applications (architecture, development, deployment, testing)
- Support teams during high workload or critical phases
- Refactor, debug, and improve existing codebases
- Design scalable, product-oriented architectures

I focus on clean, performant, and sustainable code, always aligned with business goals.

Feel free to contact me — I’ll be happy to discuss your project.
