Hi,
I have extensive knowledge of Java programming language and Object Oriented Programming concepts, I have made parallel applications in the past and will be happy to do the same for you. we can start by having me work on one of the modules and after the work is finished, you can assign me the rest based on your satisfaction with my work. This will minimizes risk of time wastage for you. I have never had a dissatisfied client yet. If you have any questions please do contact me via chat, I will be happy to answer them
