You MUST be passionate.
You dream code, you think code, you are a code pioneer ! Oh yes!

CONTEXT :
We provide the design (very modern / NY / mag style)
You are a front-end / back-end expert (or you work in small team)
We are geek and we love new tech

We work together, you can suggest changes for a better website

SKILLS
Html5
Oriented-object programming
Javascript

...
You can work with Open Sources but it must be a custom-made website.

(In order to reduce the work for the beta, we will add at the beginning a wordpress to manage the magazine)

WORKING TIME
2 weeks for Specs Sheets ping-pong
2 months project for beta Dev
20 days Testing with test-users

DEAL
We are a start-up and we have a correct budget for the Beta.
But if you are only doing this job for money, forget us.

It's an adventure and we don't look for a robot worker. Sympathy is very welcome.
Company is also open to offer some shares in case you think "it's a fucking good idea!" & you want to really be part of it.
