Back to original languageAbout Simon
Experienced Fullstack Developer, I have supported major clients from various sectors - insurance (Matmut, Helvetia), luxury (Christian Dior Couture), and aeronautics (Safran Nacelles).
My technical versatility is based on a solid mastery of JavaScript/TypeScript environments, both on the front-end (React, React Native) and back-end (Node.js), as well as a good knowledge of relational databases and other technologies.
Beyond technical skills, I distinguish myself by a strong understanding of business needs, excellent client relations, and a rapid adaptability to project contexts.
