Mat Johns is an Agile software engineer, hands-on solution architect, and a general technologist based in London. His experience with the Web reaches all the way back to his misspent youth and some rather hacktastic code, but eventually, he grew up to graduate from the University of Southampton with a master's in computer science with distributed systems and networks. Since then, he has worked for a number of start-ups on various web projects and systems, and nowadays, he specializes in designing and creating high-performance and scalable web services, currently in the Internet TV world. Away from technology, he is an avid explorer and endeavors to seek out new destinations and adventures as much as possible. He is also a qualified yacht skipper and regularly races in, around, and beyond the Solent. You can follow him on Twitter at @matjohns. Mat was also the author of the first edition of this book.
