Description

Senior React & Next.js Developer — 10 years of experience in creating SaaS applications, redesigning interfaces, and migrating legacy architectures to modern TypeScript stacks.

✨ Is your product stagnating?

Your MVP is showing its limits.Your no-code solution can no longer handle the load. Your interface is functional but not up to par. I transform existing foundations into solid applications — clean code, scalable architecture, breathing interface.

Concrete results from my latest missions:

→ 7 codebases → 1 multi-tenant platform with admin panel and business CMS (12 sites in production)

→ 24/7 secure messaging for 300,000+ health professionals (Doctolib)

→ OpenAI/Mistral integration into an e-learning SaaS — from POC to production

→ Development cycle from 12 months → 2 months, 90%+ test coverage

→ Anti-fraud solutions for B2B financial transactions

→ International teams (North America, UK, France, Middle East, East Asia)

What this means for your project:

→ React/Next.js application redesign — without breaking everything, with progressive migration

→ SaaS application development from scratch to production

→ Front-end performance optimization (Core Web Vitals, SSR, RSC)

→ Robust API development (Node.js, REST, GraphQL)

→ Consistent design system and reusable components

→ Production AI/LLM integration (OpenAI, Mistral, RAG)

→ CI/CD and testing architecture that transforms your velocity

Stack: React.js · Next.js · TypeScript · Node.js · Ruby on Rails · TailwindCSS · Prisma · PostgreSQL · Redis · MongoDB · Jest · Playwright · Docker · AWS · GCP

I challenge mockups, propose alternatives, and think about UX as much as code.
