SOA and JEE consultant

United Kingdom - Last active: 09/30/2012 - Tests: 3

Fourteen years of JEE (formerly J2EE), ten years of Weblogic, five years of Architecture. I've worked for Government and more recently in Finance architecting and designing large scale systems. I've been working with BEA (now Oracle) products since 2002 and have a very strong background in Weblogic and several of their SOA products, especially OSB I've been working with Enterprise Java since 1998 when I began at a small French web startup in Paris. In 2000, I started working for Sun Microsystems as a technical trainer running their Java certification courses. I was trained up and began running their EJB, JSP & Servlet, Patterns and Architecture courses. During my time in Hong Kong, I wrote courseware for Sun which was then delivered all over Asia. I started with BEA in 2002 where I picked up Weblogic, their integration products, their portals and latterly the SOA products. This gave me a great grounding in WebServices, XML and architecture in general. I've worked in Professional Services for BEA (then Oracle) on several large projects and for the past five years have been working as designer, architect and team lead on several high-profile projects.
