Q&A using the power of the crowdFree Question and Answer Knockout Contest

Technology

LAMP and CakePHP, OS: 2.2, Eclipse, Inbuilt SQLite database, Java, iOS: 4.2, Xcode designing tool, Objective C

Overview

We have built a Quiz platform where the wisdom of the crowd is harnessed.

Crowd Q&A is a free question and answer knockout contest. You answer one question a day and if your answer is the majority answer you are prompted to continue in the contest.

Features

The contest ends when there is only one person left. A new contest starts every day. Currently contests are open to USA residents who are aged 18 and above. There is only one account allowed per person. Contests last until there is only one player left; the winner of the contest. Each day at 7 am EST results from the previous question is calculated and a new question is posted to continue the contest.

Challenge

The Crowd Q&A web application was a daily Q&A app, with a very complex business logic, which created a daily set of users, the majority would advance and the minority would drop out based on the crowd’s response

Solution

Our innovative solution was to create an algorithm, which tracked the crowd responses and updated the state nightly. This was a play on a Finite state machine. The workflow was inspired by Mechanical Turk

Result

The application was deployed on Amazon AWS Beanstalk. The application performed flawlessly under heavy load. The business logic was flexible enough to be tweaked from a powerful user admin panel.

The costs for having my software developed by Laitkor were considerably cheaper than anything I could find in Australia. I have been very happy with the service, costs and the management of my projects
