Matthew Telles is a 20-year veteran of the software-development wars. In his time, he has seen FORTRAN, COBOL, and other dinosaur languages come and go. Currently a senior software engineer for Research Systems, Inc., his days are spent finding and fixing bugs that other people have created. Besides trying to be tactful, he also enjoys working with other developers to teach the techniques he has mastered over his career. With expertise in programming, designing, documenting, and debugging applications, he has reached the pinnacle of a programmer’s existence: the ability to write his own bio blurbs for books. He is the author of seven other programming books.
