I am creating a mobile app using ionic framework which will feature flash offers from bars and restaurants. I am using PouchDB alongside Cloudant (or if another provider offers similar/better CouchDB service I am willing to switch). The app will have a social media authentication for login. I currently have the Facebook portion built but would like to add in Twitter and Instagram. I am not familiar with CouchDB database architecture and need help with writing design documents for the queries. I will also need help optimizing performance for best user experience. This might just mean pointing me in direction of a good image caching library, etc. The scope is pretty bare minimum and mainly just need to be pointed in the right direction. I can hookup the responses from database to frontend, but need help with associations in noSQL database structure. Easy $250.

Hello, I am a RDBMS database developer trying to learn as much as I can about NoSQL data modeling (especially Cassandra). While I've learnt most of the basics of Cassandra, I'm still having some issue getting my head around how some RDBMS concepts translate to cassandra (especially simultaneous writes and lookups). I've done a lot of online research but havent found any answers. I am looking to find a cassandra (or big table) expert with for a half hour session where I can bounce all of my questions off and get some clarity on some data model concepts
