WordPress developer to enhance existing site with custom plug-ins
I am seeking a true WordPress expert to work on an existing, functioning website to fix bugs, make improvements, and enhance the service. You must be able to quickly understand the custom plug-ins which have been developed, and quickly demonstrate an ability to enhance/improve the service. You must also be very familiar with PHP and MySQL in a LAMP environment. The website uses WSDL/SOAP APIs to a back-end service, so you must have experience with similar APIs.
The website allows the updating of information in a DB, which is subsequently accessible via a smartphone scanning a QR Code. There is no mobile app development requirement since standard QR code readers are used. You must have a smartphone with a QR code reader to verify how the service is displaying after your changes have been made.
This is an active project, so additional work may follow.
You must have excellent English communication skills, have at least 4.0 feedback score, and be available immediately for this project. Please provide relevant reference sites.
Skills: wsdl, english
