{\bf \large Employment:}\\[2mm]
{\it \bf October 2006 - CERN, IT-GD-OPS} \\[0.5mm]
I have worked through out this time within the grid deployment and 
operations section of CERN's IT department.

\begin{itemize}
\item Service Manager for File Transfer Service and VO Membership Service.
    \begin{itemize}\addtolength{\itemsep}{-0.3\baselineskip}
       \item Followed CERN best practices for software deployment and configuration.
       \item Improved VOMS maintainability and reliability.
       \item Wrote new Quattor NCM components for VOMRS and YAIM configuration for VOMS.
       \item Simplified and improved High Availability Linux setup for VOMS.
       \item Identified, reported and ensured that changes needed for a reliable VOMS
             service were completed by developers.
       \item Pilot service created to field-test next VOMS service has allowed
             validation with Open Science Grid.
       \item Detailed postmortems of VOMS service incidents, actions implemented.
       \item Debug and log analysis for FTS transfer problems.
       \item Support contact for CERN's ELFMS software for IT-GD (and IT-GS).
     \end{itemize}

\item Team member of the EGEE Operations Automation Team.
      \begin{itemize}\addtolength{\itemsep}{-0.3\baselineskip}
      \item Lead integrator of OAT and public software including design and 
            control over the release cycle. 
      \item YAIM configuration for the OAT Nagios software bundle.
      \item Wrote software and tools for the OAT monitoring solution.
      \begin{itemize}
        \item voms2htpasswd, nagios-proxy-refresh and check\_ggus.
      \end{itemize}
      \item Tutorial given at EGEE 08 conference resulted in immediate uptake
            of the OAT's solution. Now 40 instances monitoring 150 sites, an exceptionally fast 
            grid deployment. Site managers are happy to install this useful service.
      \item Deployed the OAT Nagios solution in the CERN-PROD site, often the first to notice failures.
      \end{itemize}
    

\item I lead a long term project as the chair of the EGEE Worker Node Working group: 
       
      \begin{itemize}\addtolength{\itemsep}{-0.3\baselineskip}

            and the WLCG Grid Deployment Board. Regular status updates given.
      \item Production and testing of new YAIM configuration for sites to allow a richer and more
            accurate publication of their resources. 
      \item Proposed a replacement method and service for software tag publication.
            The new method is simpler to deploy and utilizes existing standard 
            middleware.
      \item Created change requests and followed up with other software providers
            checking and testing their changes were according to specification:

           \item Co-authored the compute portion of the recent WLCG installed 
                 capacity methodology. I am responsible for its implementation and deployment.
            \item The task is ongoing...
       \end{itemize}
       \end{itemize}  

\item Creating standards for operations in the wider grid community:
       \begin{itemize}\addtolength{\itemsep}{-0.3\baselineskip}
         \item I liaise with members of the Open Science Grid as part of an 
               inter-operations group.
         \item Produced standards for operating system and hardware architecture
               publication agreed by both EGEE and OSG. Rolled out by myself within EGEE.   
         \item I designed and standardized the contents of the GlueSite information system object 
               across EGEE and OSG grid infrastructures.
         \item Improved MyProxy service publication and configuration. It
               made MyProxy usable to other services beyond the gLite WMS.
         \item Represented EGEE for an EGEE/NDGF/DEISA user and operations 
               requirements document for Universal Middleware Distribution project
               planning.
       \end{itemize}
