Hi,
I have worked on Numerous Java Projects like Multi Threaded Realtime Share Market Chart, Regression Analysis kind of Project for my college work. I am right now working with Android & Java Swing. I don't think that i should mention any portfolio here for this project. Than also if you need than let me know i will get back to you. You can check that on Github for my public projects. i.e. GITHUB/vintesh.
I can start as soon as you want. Looking forward to hear from you.
Thanks,
Vintesh
