About the Authors
Odili Charles Opute started his IT career with web technologies in 2003, after obtaining a

degree in Computer Engineering from the University of Benin. Having successfully completed the
Enterprise Java track in NIIT, Benin, he joined Digitanx Systems in 2006, where he led Java and
Mobile development, in 2006. In 2007, he embraced the freelance game, consulting for several
agencies and development shops while still experimenting with other non-Java technologies.
He later moved to Port Harcourt city, in late 2008, and joined XChequer, a vibrant startup hoping
to change the mobile landscape in Africa with NFC-powered contactless payment solutions.
Whilst in XChequer, he was responsible for cutting-edge web solutions and led the
development of the NFC prototypes. He currently works with the University of Benin
as one of the webmasters, but with the specific responsibility of strategy, design, and
integration, and as the development lead for the institution's online presence.

This book has really come a long way. I want to thank God for making it a
reality and to specially acknowledge my family for their support. This would
also not be complete without mentioning Anita: thanks, honey, for your love
and understanding.
