About
Sylvain Joffraud
Senior Full-Stack Developer
Full-Stack developer passionate about the web for 25 years, including 18 years of professional experience. I help teams and companies design, harden and scale their applications — fully remote.
My approach
Reliable, shipped and maintainable products.
I specialize in React, Node.js and PHP/Symfony, with strong expertise in modern architectures (DDD, hexagonal, Clean Architecture), CI/CD and DevOps.
Over 18 years I have built payment back-offices, high-traffic e-commerce platforms, B2B booking tools, PIM/MDM systems and healthcare solutions. I work both fully autonomously and within product teams.
My priority: ship robust, maintainable applications, reduce technical debt, and stay transparent — I provide a daily activity report.
