Is your web project stagnating? Do you need a developer capable of taking on acomplex applicationor **building a product from scratch to deployment**?
I work as a full-stack developer to designcustom web solutionsthat are robust and scalable — whether starting from a simple idea or an ongoing project.
With **15 years of experience in web development**, I have worked in a wide variety of environments:
- Large corporations (Air France, SNCF, Renault Digital, Accor-Hotels, Publicis)
- Startups & scale-ups (Whoz, Beta-Gouv)
- IT Service Companies & consulting (Capgemini, Atos)
This diversity allows me to adapt quickly toyour context, understand your business challenges, and deliver concrete results— such as the 4x increase in customer satisfaction at SNCF.
I have contributed to the development of various web projects in **React.js, Next.js, and TypeScript**:
- SaaS applications & custom business software
- Microservices architectures
- Dashboards, reporting tools, and API integrations (Stripe, Google...)
- Performance optimization and debugging of existing applications
My approach: a stable, documented, and scalable **turnkey product**, with AI automation (AI agents, RAG) — without wasting your time on recurring technical issues.
Tech stack: React.js, Next.js, TypeScript, JavaScript, PostgreSQL, MongoDB, ElasticSearch, Tailwind CSS, Bootstrap, Shadcn, Prisma, Supabase, Sequelize, Stripe, Lemon Squeezy...
