CERN, Geneva - Switzerland

Since September 2009 I am working as fellow at CERN in IT/Grid Technology group, in section responsible for certification, testing and releases of the gLite middleware (grid middleware used in LCG), and the ETICS system development (used for building and testing gLite). I am working mainly as a sysadmin - I manage CERN certification testbed running a number of GRID services (SEs, CEs, WNs, WMS, DPM,...). Currently I am also maintainer of the vNode project - system for managing Xen virtual machines, and I am responsible for group's virtualization infrastructure (based on vNode and Xen) used mainly in release process and development of gLite. I am also involved in computer security - I manage system automating firewall rules generation for machines running grid services. In the past I did some programming in C/C++, Java, Perl, SCL (Siemens PLCs), PHP, and SQL. Being a sysadmin I do also bash scripting and recently I started using Python. I use mainly GNU/Linux (since over 10 years), occasionally MacOSX, but I also used (or at least tried) other operating systems (mostly u*x-like, but I also use MS Windows if I have to ;-)
