Hello,
I am very familiar with java and multi-threaded applications. I am currently working for a software company who's products consist of an enterprise suite of applications that are all mainly large-scale, multi-threaded, and socket-based programs. Java has been my main programming language since I started and I am very fresh and current when it comes to java and thread programming. I would be a great candidate to produce this small mock-elevator application.
I hope to hear from you soon,
Justin
