Twitter Sentiment Analysis using Kinesis Stream in RoR

Have to build Twitter sentiment Analysis using Kinesis stream with RoR. Do we have any git repo for Kinesis producer in RoR which I can use?

Is there any Gems list of RoR which I can use to achieve this?

Also, I don't have to use Elastic search or Firehose. Have to do it using Kinesis Stream which will save Twitter content on S3 and then probably by Lambda I can have data back to EC2 for showing the analytics.

Please let me know if approach have issues or there is any way other round it.
