In 2002, Escape Velocity folded, and I ended up going back to CERN (not a big move, since at the time I was working remote from Chamonix, France). I joined the Grid Data Management Work Package of the European Data Grid Project. My main area of work was writing J2EE based architectures for Data Replicaton in Grids. I authored an ant-based build system including web services integration. This again used our home-grown Continuous Integration build system. This involved approximately 2000 lines of ant scripts to do the full build, release and packaging cycle for 120,000 lines of code.

I also was responsible for the development of Grid Catalogs for the project, written in Java, with Oracle + MySQL backends via JDBC. These now support the deployed Grids used daily by the CERN physics community.

The EDG project finished in December 2003, and I was then involved in supplying Oracle based services to the physics community at large. A lot of this involved supplying expert knowledge on the Oracle J2EE Application Server.

As of May 2005, I have been rehired within the Grid Deployment Group at CERN, working again on Data Management systems, but with a focus on deploying stable solution for the LCG-2 Grid Infrastructure.
