Opa Developer Challenge



The Opa Developer Challenge's objective is to develop an application with Opa, the new open source framework for JavaScript.  It is also to enable the developers to keep on working on it once the challenge is over thanks to awesome and useful prizes; and maybe even create a start-up.  If you wish, your code will remain confidential -- the judges and admins will only access it for the purposes of administering and scoring the challenge.
The theme of the application is entirely up to the participant's creativity. However, if your application uses the Box API, you are also eligible to win the special prize: a 5-seat enterprise Box account for life*.

Top prize is a $5,000 Amazon Web Services coupon, 2nd prize is a one month free café membership at NextSpace, and 3rd prize is an Amazon Kindle Fire.  In addition, the first 100 participants who submit a fully-working app will be rewarded with a $50 AWS coupon (limit of one coupon max per person).

PLEASE NOTE: All prizes will be fulfilled by the sponsor of this challenge (MLstate, the creators of Opa) and their partners.

What is Opa?
Opa is the ultimate framework for JavaScript. 
JavaScript is becoming the universal language, with technologies such as Node.js and MongoDB. Entire, modern applications can now run JavaScript from end-to-end. JavaScript and Node.js are outstanding but there is still a major problem to solve: Node.js hangs and faces bugs + safety issues. 
The solution is Opa, the ultimate enterprise framework for JavaScript. Thanks to its code verification and its code automation, create a web app is simpler, safer, more secure and it considerably reduces the risks of XSS attacks or SQL injections for instance. Your code is much shorter, much better and much safer.
