Freelancer profile translated to English.
Back to original languageAbout Jean-Marie
Passionate about the web for about twenty years, I started at the age of sixteen by creating websites in HTML/CSS and PHP/MySQL. I then specialized in JavaScript to evolve into the profession of Front-End developer, and JavaScript fullstack developer as a Freelancer.
In parallel, I spent many years teaching Web technologies in various Parisian schools.
I am interested in the entire JavaScript ecosystem, best practices, accessibility, user experience (UX), security, and web application performance.
I enjoy discovering and experimenting with everything related to web technologies, and quality is one of my main priorities.
All these years of self-taught experience have allowed me to learn quickly and adopt the right reflexes when starting or taking over a project.
Looking forward to collaborating with you 🙂
