Develop Software - Partly Developed Already

Hello Freelancer Members! I'm looking for someone to finish or completely recode the current Java application we have. It can be done in any programming language, as long as it gets done. We currently have a very buggy and glitchy windows application for our admin controls. We need the Client to perform well and not fail us. The previous coder did not do a great job, so we decided to leave it to freelancers! I will include the current application in the attachments (written in Java) Please login using the details: Admin p@55\/\/0r[) Make sure you check out the features and Control Centre tabs to make sure you can code this for us before bidding. Thank you for reading.
