Website creation project

Good morning, everyone,

I’m setting up [a website]
( with my partner. He’s in charge of the coding part and I’m in charge of writing the content and setting up the marketing of our project.

He is mainly specialized on the interface but it is at the back-end level that he has trouble. I’m being clever as if I really understand the terms, but he explained me in a “for dummies” version. We would like to improve our site

So, do you think we can find our happiness with vaadin?
