Colin Yates is a J2EE principal architect who specializes in web-based development. He has been a freelance consultant for the past three years and has worked in a number of environments, both structured and chaotic. Since graduating with a software engineering degree in 1997, he has held a number of positions, including development lead, principal systems engineer, mentor, and professional trainer. His principal skill set includes mentoring others, architecting complex problems into manageable solutions, and optimizing development processes.
Colin was first introduced to the Spring Framework in January 2003 by his mentors, Peter Den Haan and David Hewitt, and he has never looked back. After a couple of years using the Spring and Hibernate technology stack to good effect, in May 2005 he became one of the early adopters of Spring Web Flow, finally finding the missing item in the web development toolbox. A self-confessed addict of the green bar that comes from following test-driven development and XP, Colin regularly frustrates new team members by introducing a continuous build environment.
When not hanging around the Spring support forums (http://forum.springframework.org), Colin can be found out walking with his wife and two dogs, practicing martial arts, attending his local church, or preparing for the arrival of his first child.
Seth Ladd is a software engineer and professional Spring Framework trainer and mentor specializing in object-oriented and testable web applications. He started his own company building websites at age 17, but now enjoys having a real job. Currently working for Camber Corporation, Seth has built and deployed systems for NEC, Rochester Institute of Technology, Brivo Systems, and National Information Consortium. He has architected and developed enterprise applications in Java and C for both the server and remotely connected embedded devices. He enjoys speaking and teaching, and is a frequent presenter at local Java user groups and at corporate developer conferences. Seth is very thankful for living and working in Kailua, Hawaii, with his wife.
Steven Devijver is an experienced Java developer who started developing J2EE applications in 2000. In 2003 he discovered the Spring Framework, and since then he has been one of its most enthusiastic users. Steven is a senior consultant at Interface21, teaching hundreds of students every year about the Spring Framework.
Darren Davison is a principal consultant for UPCO, specializing in J2EE and open source Java technologies. He has been involved with Spring since the summer of 2003, well before its 1.0 release, and he used the framework to underpin a global intranet site for an investment bank. Darren has previously worked for multinational manufacturing and engineering companies on e-business, infrastructure, and many web-based projects. Away from work, Darren enjoys the never-ending journey of discovery that is GNU/Linux. When not in front of a computer screen, he likes reading and any form of live entertainment.
