IMMEDIATE START - DELIVER IN 3 DAYS We require a mobile app/node js developer to work on our server end and web admin. SCOPE Implement News/Comments and Like functionality into our existing Loopback API framework. This involves full backend implementation; analysis; unit tests; administration web end and assist in integration with our mobile app. FUNCTIONALITY Loopback JS framework: 1. Allow display and writing of Comments for other content types (ie comments on a news article, comments on a survey etc) 1. Allow upvote/down vote and Like and Unlike of content types (ie like a comment, unlike a news article, like/unlike a survey etc) 3. Create/display html5 content News which supports images, different categories of news (ie sports, business etc: the exact category type should be changeable) 4. Image management (upload, display edit etc) needs to come from a service provider and can do auto scaling ([login to view URL], [login to view URL], Windows Azure/ AliCloud / or others) 5. For all the above models (Comments, Likes, News) they should be filterable/sortable and ranked (ie top 10 content types with MOST LIKES, MOST COMMENTS in the last 24hours, month and year) 6. Provide us a simple web based administrative end to the above 10.
