Urgent: Need a Java expert

We have a project mostly programmed with java which takes the role as a middleware between the IMU device and the platform. Freelancer should be able to take the project we provide as a starting point, change and update some features and do the full test before deploying. If you are an expert with Java, feel free to join us.
I will check each and every proposal, "CLASSIC PROPOSALS WILL AUTOMATICALLY BE IGNORED".
Knowledge of IMU device and socket.io experience with java will be a huge plus.
