Troubleshoot/Rewrite NodeJS RabbitMQ MongoDB Crawler Process

We have a master process that using Nodejs app to query Mongodb and then extract data to and add the data to a queue in a RabbitMQ process each hour.

The queue has N subscribers (crawlers) who take the next available message, process the job and write a result back to Mongo.

The developer who implemented this used a Mongo ORM (Caminte) which does not support some critical MongoDB functionality.

We need someone to rewrite the Mongo queries using the native driver and troubleshoot the job to ensure that it works.

Skills: node.js, NoSQL Couch & Mongo
