Write a wordpress plugin that exposes internal API functions

We need a developer with experience on writing wordpress plugins. We are searching for someone to maintain a longer relationship with several projects. We have an existing API written in the java-based LifeRay platform and want to write a wordpress-plugin-frontend to visualize that information. The plugin should work similar to this: - Should have a settings page where you configure a general API-username/password to the API - A user should also be able to authenticate themselves as an individual user to the API since information is fetched by user. This is not solved yet, lets discuss best method together. - Should implement shortcodes that call the respective underlying API-function with parameters - For each shortcode (or API function), a different HTML template should be used to view the results - It should be possible to upload documents to the API. If this is possible by using shortcodes too, its great. Otherwise use any other means of uploading documents through the wordpress frontend. - Add support for printing documents downloaded from the API. If this is done through this newly written plugin or by installing an already made plugin doesn't matter. - The full specification is not ready. We will collaborate with you to establish a full specification. The person needs to be: - An experienced PHP-programmer (5+ years) - Experienced in writing wordpress plugins (2+ years) - Documented experience in implementing REST/JSON API - 100% communicative in english ---- REQUIREMENTS ---- We will only hire individual freelancers. Companies providing teams of developers will not be considered. You will need at least two LifeRay-related freelancer reviews in your profile to apply. Please do not contact us through Skype/LinkedIn or other media before project ends. Doing so will result in your bid being discarded.
