Sébastien worked on Html/Sass/JS for a public ASP.NET MVC web application (B2C and B2B): the YouScribe site, as part of a maternity leave replacement.
Sébastien is very professional, he understands quickly, is responsive and flexible, in addition to being very competent in web integration, JS, and SEO.
I recommend Sébastien without hesitation.
