Crowdsourcing can be an incredibly efficient way to build cloud applications. Let’s pull back the curtain and take a look at exactly how this new model translates community-driven challenges into real results.

MESH01 – A CROWDSOURCING OVERVIEWMESH01 recently built their innovative new platform using Topcoder as their development engine. Running competitive crowdsourcing challenges as “sprints”, and getting a community of 600,000 technical experts to contribute code allowed MESH01 to build their application on cutting edge technology (including AngularJS, Node, MongoDB, and Heroku) at half the expected time and cost.

MESH01 DEVELOPMENT

“The work that Topcoder completed in three months was equivalent to approximately 15 full time developers, and the community delivered a platform at nearly half of the estimated cost.”

— Brian Bednarek, CEO of MESH01

Data Point Editor I [user interface functionality]

Add colored points (markers) to images and store the marker locations relative to the image and the user in a database. The rules behind these markers can be complex, so we are going to simplify this first challenge as much as possible. You will use AngularJS,Express and mongo to add red, green or grey points as an overlay to an image displayed in a carousel.

API Versioning + Security [API]

Start with our base api version 1.4 goat which can be found in poost registration details. Two new features will be added: api key, and password hashing. Limit their availably by passing in the version 1.5.0 via the header. By not passingin the version in the header, version 1.4 should be returned (default) however by passing in 'accept-version 1.5.0' in the header, you will be required to also include the api-key as well as hashing the password when a new user account is created.

Simple Batch Processor with Scheduler, Queue and node.js [Batch auto-email]

Using an off-the-shelf scheduling system (simple, cron-like), an off-the-shelf Message Queue (Heroku addon like RabbitMQ), and an email sender like SendGrid, build a process that evaluates each wear test on a daily basis, and sendsa notification to each participant who has not submitted an activity log in the last 7 days.

Worker + Queue Refactoring [platform]

Consolidate and re-factor two queues and their corresponding worker into a single queue and a single worker. These workers each perform a similar function which we will discuss later. With refactoring, we will be able to process more efficiently as well as add new conditions for notification.
