Dear Upworkers, Please read the job description carefully. Project Background: =================== We have developed a social application ( android ) and currently All api’s entrance are on the script api.php, that has the shorts as below at least,
1. not good performance, for each request, must load all controllers (do that on the __construct method of the api class ).
2. very bad code structure, with lots of if/else or switch/case. Now we want someone to import all existing API to Doctrine and use CI (REST_Controller). So we need clean, well organized code with super performance. Project Details: ================= Please open the google spreadsheet: https://docs.google.com/spreadsheets/d/1THt21pXZDf8n-rOUQgMGY3KAWR-j7gpmZcY1G3AkM_4/edit?usp=sharing Along with the performance improvements that I mentioned above, We'll need you to develop all the APIs from the "Enhancement" Sheet and fix all the bugs from the "BUGS" sheet. The developer must be familiar with CDN, AWS S3, PHP, CodeIgniter , git,bitbucket and Doctrine. Please don't apply if you are not sure you can do this and just want to try. These APIs are related to an android app. So basic knowledge about android , chat server and java would be a plus point I think. Please put rockstar at the beginning of your cover letter, so that I know you read the whole post. Thanks.

I need a developer to help create an android app that pulls (somewhat) real-time stock quotes and RSS news for a user-defined subset of stock symbols. I know what I want the app to do and have the basic look and feel designed. I just need someone to build the back-end. Experience with stock market APIs and RSS news feed aggregation is a plus. I would plan to work hand-in-hand with the developer so we can together solve any problems/issues that may arise.
