Sal Mangano has been developing software for over 12 years and has worked on many mission-critical applications, especially in the area of financial-trading applications. Unlike many XML/XSLT developers, he did not approach the technology from the standpoint of the Internet and Web development but rather from the broader need for a general-purpose, data-transformation framework. This experience has given him a unique perspective that has influenced many of the recipes in his book, the XSLT Cookbook. Sal has a Master’s degree in Computer Science from Polytechnic University.
