Hello,
I think i can help you: you need a fully javascript application and i'm french developper (Brittany) 4 years experienced on this particular technology.
With a week of work, we can create a structured architecture like a "responsive one page application", a "session manager" for users, and a "quizz framework"
A second week will be needed for an administration tool to post question/answer, and tests the all app.
I can't correctly pay my-self without 1000$ a week. Expensive compared to certain international workers, but it's a guanrantee of quality.
1) My code is clean, modular, with best practices, commentary, fully readable and reusable by an other javascript developper
2) I'm very available: always on skype and gmail; My english understanding is total. My expression more limited, as you can see. Please give me written and detailed explanation on what you need, what must be modified, what is a bug, and i can do/repair it !
3) I'm passionate by what i do : your app will be at the cutting edge of technology : html5/css3, bootstrap, nodejs, mondogb, meteor...
4) I hate bad commentary on my profile : I'm very attentionate about what you expect and we don't stop until you are satisfied.
See you very soon !
Loïc
