I do end to end development in Java and Javascript (jQuery, EJS, express.js, MongoDB). I have a strong track record in developing analytics applications involving web scraping, charting, reporting and BI.
I also do native Android apps as well, for a demo of some the code I've written you can check this - https://github.com/divyad .
However, most of the code I've written is for proprietary projects.
Please contact backoder @ gmail.com if you have any requirements; I can start immediately.

Extensive experience with startups in the nascent phase, helping them build prototypes.
Skills - backend programming in node.js, Python, and Java, limited front end experience.
At this point I've worked with 3 startups helping them build their initial product versions.
* Currently doing a project for a startup in NY for their analytics pipeline with Node.js and Mongo
* Worked for two startups in Singapore, both in the Social Media domain. I worked primarily in Python and focused on web crawling, scraping, NLP (topic extraction and sentiment analysis), search infra with Solr
* I can help with analytics, query tuning (MongoDB, HBase, Postgres, Oracle)
* Bonus - I have lot of expertise in Hadoop and the related ecosystem, as I work on that on my day job
ElasticSearch itself should be very good now since they have moved to Lucene 4.0 which brought in lot of improvements in memory usage.
I evaluated elasticsearch for RT analytics. It works wonders for point queries, where your result set is going to be small. Didn't work well for aggregate queries which need to scan lot of data. The biggest problem was field cache in Lucene. Almost all our queries needed to fo faceting which had a big impact on field cache.
Also, I don't know about Riak, but in ES the joins you can do are very limited.
I'll do extensive testing, but I need to scan a lot of data (aggregate basically). I'd be comfortable even with index size in multiples of data size if it delivered RT queries. Have you evaluated anything else?
I was looking at Impala (Cassandra) as well as keeping an eye on Drill progress. My data is write only in ETL stage so it seems it could be the right way. Lots of testing ahead! - thanks
