Description

Hello,

I am a Freelance Front-end Developer and Web Integrator in Paris, and I invite you to consult my CV in French here: chechucastro.com

I am passionate about web culture and have focused on "front-end".

More motivated by the function than the status, I wish today to offer you my web skills.

By nature open and cheerful, I love my job which I would even call a passion.

I am at your disposal for any further information.

Sincerely,

Chechu Castro
