Hello! My name is Kevin Fisher. I am a student of computer science at the University of Memphis in Tennessee. I have experience in decompiling .JAR files and both modifying existing behavior and reverse engineering the behavior into new programs. Please contact me before accepting the bid- I would like to look at the JAR first if possible. I want to see if the original developer added in any obfuscation (tricks to make it harder to decompile). You can contact me on this website or on Skype. My skype is: megabytefisher. Thanks, Kevin Fisher

I have previously worked on sending email with attachment. We can discuss in detail . If its just about the attachments then I can do in one day.

I have three years of experience in java and am well versed with hands on. I have experience in working on all of SDLC.

Assuming the program is already working, implementing attachments should be doable. Hope to ear from you soon! ;) Best regards, Sandro Marques
