Description

💎 Does your project deserve better than AI-generated code without guardrails?

I develop web applications with the rigor of Software Craftsmanship: clean code, solid architecture, long-term maintainability.

📅 Available for one-off or recurring missions - Remote or Strasbourg.

✅ 10+ years mastering React/Next.js, Node.js, and TypeScript

✅ Code review, automated testing, hexagonal architecture, DDD

✅ Code audit and refactoring of existing bases

✅ Multiple experiences in startups (beta.gouv/DINUM, sweep.city, Baback...)

My philosophy: Well-written code today = Easy evolutions tomorrow = Maximized ROI.
