Need a developer for an existing application in Node.js

Hello, I need you to make some changes and fix some bugs in the admin section of my android app which is done in Node.js along with some other changes in the admin area, which is more or less web based work. If you apply for this job, please make sure that you are an expert in PHP, Node.js, JSON, mySQL, HTML and CSS. Web socket programming has to be done. This admin area is for my android app, so you will be working with my android developer and provide him the values in some variables which he can access in android side app. Please do not waste my or your time if you don't work on the above technologies. I will prefer full time developer over part timers. Will share more details about the project, once we get connected. Thanks
